    A chitosan-based composite for adsorption of uranyl ions; mechanism, isothems, kinetics and thermodynamics
    (Elsevier, 2021) Senol, Zeynep Mine
    The present paper describes a green and cost-effective approach to investigate chitosan-sepiolite (Ch-Sep) composite as an adsorbent for removal of UO22+ ions in aqueous solution. The Ch-Sep composite was prepared as a beads using with two cross-linking agents: tripolyphosphate (TPP) and epichlorohydrin (ECH). Their adsorption properties for the removal of UO(2)(2+ )ions in aqueous solution by batch experimental conditions were studied. The adsorptive removal processes of UO(2)(2+ )ions from aqueous solution were evaluated by Langmuir, Freundlich and Dubinin-Radushkevich isotherm models, and was found to be perfectly fit to the Langmuir model (R-2 = 0.971). The maximum adsorption capacity was 0220 mol kg(-1) at 25 degrees C from Langmuir isotherm model. Adsorption energy was 12.1 kJ mol(-1) indicating that the adsorption process was chemical. The adsorption kinetics followed the pseudo second order and infra particle diffusion models. The thermodynamics parameters of UO22+ ions removal from aqueous solution was confirmed spontaneous, endothermic and possible at higher temperatures behavior of adsorption process. The adsorption mechanism of UO(2)(2+ )ions onto Ch-Sep composite beads was investigated by FT-IR and SEM analysis. These findings revealed the effectiveness and potential of the newly synthesized Ch-Sep composite beads for the removal of UO22+ ions. (C) 2021 Elsevier B.V. All rights reserved.

    (Springer, 2020) Senol, Zeynep Mine; Gul, Ulkuye Dudu; Gurkan, Ramazan
    Bisphenol A (BPA), which is known as one of the endocrine-disrupting chemicals (EDCs) with hydrophilic hydroxyl groups and hydrophobic aromatic groups, has been widely used in plastic industries. The chemical waste from the industry is sometimes discharges into lakes and rivers, and then these surface waters can be polluted. So, this article aims to investigate the bio-sorption process of BPA by the inactivated lichen (Pseudoevernia furfuracea) biomass from aqueous solution. At initial, the effect of the variables such as initial BPA concentration, solution pH, temperature, contact time and recovery rate on the bio-sorption process was investigated. From the optimal results, it has been observed that the highest removal efficiency is approximately 64% at a contact time of 3-h, the bio-sorbent concentration of 9 mg/L, initial BPA concentration of 40 mg/L, and agitation speed of 150 rpm at pH 5.0. In explaining the bio-sorption potential of lichen biomass, Langmuir and/or Redlich-Peterson isotherms with two and three parameters, respectively were observed to be better fit with the experimental isotherm data (R-2 = 0.982). From equilibrium data based on difference between the measured and predicted results (q(e, exp)and q(e, pre)), it was shown that biosorption of BPA could be best described by the pseudo second order kinetic model with minimum sum of square error of 2.61%. In addition, it shows more film diffusion, and partly pore diffusion in linearity region in terms of kinetic sorption behaviors of BPA in the rate-limiting step as well as intra-particle diffusion according to Boyd's kinetic model with better regression coefficient than 0.981 when compared to the other used kinetic models, including Bangham's pore diffusion and Elovich kinetic models (with R(2)of 0.958 and 0.929). The thermodynamic studies showed that the biosorption process was spontaneous, and chemically feasible. Therefore, due to be low-cost, eco-friendly character, wide availability and easily accessible, the lichen biomass could be used as a promising bio-sorbent for the removal of BPA from the environment and wastewater effluents.

    (Taylor & Francis Ltd, 2023) Senol, Zeynep Mine; Keskin, Zehra Seba; Sarac, Kamuran; Simsek, Selcuk
    In this study, the biosorption properties of fast green FCF (FG) dye in an aqueous solution were investigated using cranberry (Cornus mas L.) kernel (CK) as lignocellulosic biowaste. The biosorbent performance of the cranberry (Cornus mas L.) kernel biomass for FG dye molecules was optimized: 500 mg L-1 at natural pH: 6.0 at 25 degrees C. The maximum biosorption capacity for CK biomass was found to be 21.6 mg g(-1) from the Langmuir isotherm model. Biosorption thermodynamics showed that FG dye biosorption to CK biomass was spontaneous, entropy-increasing, and endothermic. The kinetic data were described by the PSO and IPD kinetic models. Thermodynamic parameters were calculated, and it was seen that the biosorption process is spontaneous and endothermic. FT-IR spectrum after biosorption provided data supporting the formation of electrostatic interactions, n-pi interactions, and H-bonds between anionic FG dye molecules and CK biomass. When the results of this study were evaluated as a whole, it was concluded that CK biosorbent is a natural, abundant, low-cost, effective, and potential biosorbent for the removal of FG dye molecules from wastewater.

    The current study aimed to investigate the biosorption of rhodamine B from aqueous solution using an almond shell as an agricultural solid waste biosorbent. The almond shell biosorbent was characterized via Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM) with energy dispersive X-ray (EDX), and point of zero charge (pH(PZC)) analyses. The parameters that influence the biosorption process such as contact time, initial dye concentration, biosorbent dose, temperature, and pH were investigated. According to the correlation coefficient, the data were best outlined by the Langmuir isotherm with adsorption capacity of 14.70 mg g(-1). The adsorption energy found from the D-R model showed that the adsorption process is chemical. The kinetic data were described by the pseudo-second-order kinetic and intraparticle diffusion kinetic models. Thermodynamic parameters were calculated; it was seen that the biosorption process is spontaneous and endothermic. The density functional theory (DFT) calculation results are well-matched with those discovered through experimentation.

    Biosorption of rhodamine B and sunset yellow dyes on cross-linked chitosan-alginate biocomposite beads: Experimental and theoretical studies
    (Elsevier, 2025) Senol, Zeynep Mine; Arslanoglu, Hasan; Keskin, Zehra Seba; Mehmeti, Valbone; El Messaoudi, Noureddine
    This research explores the biosorption of Rhodamine B (Rd-B) and Sunset Yellow (SY) dyes using cross-linked chitosan-alginate (Ch-A) biocomposite beads, combining experimental investigations with theoretical studies to elucidate the biosorption mechanisms. The biocomposite beads were synthesized through an eco-friendly cross-linking method, and their structural properties were characterized using various characterization techniques. Complementary theoretical studies using Monte Carlo (MC) simulations and molecular dynamics (MD) calculations provided insights into the molecular interactions between the dyes and the biocomposite beads. ChA maximal biosorption capacity for Rd-B and SY was determined using the Langmuir model to be 43.6 mg g- 1 and 25.1 mg g- 1, respectively. Kinetic analysis elucidated that the biosorption process for Rd-B followed the pseudo first order (PFO) model and SY followed the pseudo second order (PSO) model. According to the thermodynamic characteristics, Rd-B and SY adsorb spontaneously and endothermically on Ch-A. In conjunction, MC and MD calculations were applied to probe the interactions between Rd-B and SY molecules and the Ch-A biocomposite beads, providing compelling evidence of robust binding interactions such as hydrogen bonds, electrostatic attractions, and it-it interactions. These theoretical insights were subsequently aligned with empirical observations, affirming a significant relation between the theoretical and experimental data. This study highlights the significance of combining experimental data with theoretical models to advance the development of environmentally friendly materials for water purification.

    (Elsevier, 2024) Cigeroglu, Zeynep; El Messaoudi, Noureddine; Senol, Zeynep Mine; Baskan, Gulsah; Georgin, Jordana; Gubernat, Sylwia
    The discharge of dyes and antibiotics (ATBs) into the water streams causes severe water and soil pollution, which poses a global threat to aquatic ecosystems and humans. Clay-based nanomaterials (C@NMs) exhibited great potency as adsorbents to sustainably eradicate dyes and ATBs from water bodies and waste sites due to their large surface area, tunable porosity, and surface reactivity. Various types of clay minerals and their modifications to engineer NMs with tailored adsorption properties are extensively explored. Comparative studies with conventional adsorbents further underscore the superior adsorption performance of C@NMs. In addition, the underlying adsorption mechanisms and intermolecular forces governing how the adsorbent and adsorbate interact are elucidated. In terms of views, the review likely highlights the significance of developing efficient and costeffective methods for removing pollutants from water sources, considering the increasing concerns about water pollution and its detrimental effects on human health and the environment. Looking to the future, the review may suggest areas for further research and development in the field of C@NMs for water purification. This could include optimizing the synthesis methods to enhance the adsorption capacity and selectivity of these materials, exploring novel modification techniques to improve their performance under different environmental conditions, and conducting more comprehensive studies on the long-term stability and recyclability of C@NM adsorbents.

    The UO22+ biosorption properties of a lichen, Evernia prunasui, from aqueous solutions were investigated. The widely occurring lichen samples were collected from the forest in Bilecik-Turkey. The UO22+ biosorption onto lichen was characterized by FT-IR and SEM-EDX analysis techniques before and after biosorption. The effects of the solution pH, biosorbent dosage, UO22+ concentration, contact time, and temperature on UO22+ biosorption on lichen sample were studied by using the batch method. The isotherm experimental data were described using isotherm models of Langmuir, Freundlich and Dubinin Radushkevich. The maximum UO22+ biosorption capacity of the lichen sample was estimated by the Langmuir equation to be 0.270 mol kg(-1). The adsorption energy from the Dubin Radushkevich model was found to be 8.24 kJ mol(-1). Kinetic data determined that the biosorption was best described by the pseudo-second-order kinetic model. Thermodynamic findings showed that the biosorption process was endothermic, entropy increased and spontaneous. In conclusion, the lichen appears to be a promising biosorbent for the removal of UO22+ ions from aqueous solutions because of high biosorption capacity, easy usability, low cost, and high reusability performance.

    (Springer Heidelberg, 2024) Senol, Zeynep Mine; Arslanoglu, Hasan
    In this study, a zero-cost, naturally effective adsorbent, sand leek (Allium scorodoprasum L.), was used for the effective removal of lead ions from an aqueous solution. This natural adsorbent was characterized by FT-IR, SEM-EDX, and PZC analyses. Batch studies were conducted at one factor at a time to explore maximum removal efficiency in terms of pH, initial lead(II) ion concentration, contact time, adsorbent dosage, and temperature for efficient adsorption. The maximum lead(II) ion uptake capacity for SAC was obtained at pH 4.5, initial lead(II) ion concentration at 1000 mg/L, operation time of 1440 min, adsorbent dosage of 10 g, and temperature of 25(degrees)C. The adsorption data were well-fitted by the Freundlich isotherm model, with an R-2 value of 1.000, indicating a good fit. The kinetic study revealed that the adsorption of lead(II) ions followed a pseudo-first-order kinetic model, with an R-2 value of 0.9746. Furthermore, the thermodynamic parameters including Gibbs-free energy change (Delta G(degrees)), enthalpy change (Delta H-degrees), and entropy change (Delta S-degrees) were calculated to demonstrate that the adsorption of lead(II) ions onto natural adsorbent was endothermic and spontaneous.

    In this study, the use of fungal (Panaeolus papilionaceus) biomass as a biosorbent was investigated to effectively remove Pb2+ ions from aquatic medium. The removal of Pb2+ ions using a fungal biosorbent was examined in a batch system in terms of initial solution pH, temperature, time, and initial Pb2+ concentration. Optimal operating conditions for biosorption of Pb2+ ions; pH: 4.5, T: 25 degrees C, and t: 24 h. The max biosorption capacity for Pb2+ ions was found to be 31.2 mg g(-1) from the Langmuir model. Thermodynamic studies showed that Pb2+ ions biosorption into fungal biomass was possible, spontaneous, and endothermic. Additionally, the antimicrobial activity and antibiofilm activity of the extract of fungus were also investigated. It was determined that the fungal extract did not have antimicrobial properties. On the other hand, the extract has been shown to have the potential to prevent biofilm formation. 1 mg of the extract prevented the biofilm formation of Staphylococcus aureus by 87.85%. It has been observed that the biosorption mechanism of Pb2+ ions into fungal biomass includes the steps of surface biosorption, film diffusion, and intra-particle diffusion.

    (Elsevier Sci Ltd, 2020) Senol, Zeynep Mine; Simsek, Selcuk; Ulusoy, Halil Ibrahim; Mahmood, Ayyaz; Kaya, Savas
    Applications of a hybrid material consisting of polyacrylamide (PAA) and Xylidyl Blue (XB) for the removal of uranyl ions from aqueous solutions has been investigated with all details. Adsorption experiments were performed at batch mode and constant temperature. Experimental parameters affecting adsorption process such as pH, initial uranyl concentration, time and temperature were studied on the removal of the uranyl ions. The isotherms assays were carried out with synthetic solutions and adsorption data were evaluated by using Langmuir, Freundlich and Dubinin-Radushkevich (D-R) isotherm models. Morphological and chemical characterizations of new synthesized material were investigated by UV-VIS-NIR spectroscopy and SEM/EDX techniques and pH(pzc) experiments. The results of the kinetic experiments are consistent with pseudo-second-order models and intra-particle diffusion models with a slightly better fit to the latter. Equilibrium was achieved within 3 h. The value of rate constant for adsorption process was calculated as 1.055 mol(-1) kg min(-1) at 318 K. The calculated thermodynamic parameters (Delta G degrees, Delta H degrees and Delta S degrees) indicated that the adsorption of uranyl ions onto XB@PAA was feasible, spontaneous and endothermic nature under the studied temperature. The developed material has also a potential as a sensor because its color turn from pink to red by adsorption of uranyl ions.

    Optimization the removal of lead ions by fungi: Explanation of the mycosorption mechanism
    (Elsevier Sci Ltd, 2021) Senol, Zeynep Mine; Gul, Ulkilye Dudu; Gurbanov, Rafig; Simsek, Selcuk
    The potential utilization of fungal biomass (Rhizopus arrhizus) as a biosorbent for the efficient removal of lead (Pb2+) ions from aqueous solutions was optimized in the current work. The maximum Pb2+ biosorption capacity of fungal biosorbent was 0.501 mol kg(-1) at pH 4.0 and 25 degrees C. The biosorption process follows the intra-particle diffusion and pseudo-second-order rate kinetics. Thermodynamic studies showed that Pb2+ biosorption by this fungal biosorbent is spontaneous and endothermic. The fungus has good biosorption/desorption performance for Pb2+ ions according to desorption studies. The biosorption free energy calculated from the DubininRadushkevich isotherm showed that the biosorption process was accomplished chemically. Moreover, the mechanism of the Pb2+ biosorption on to the fungal biosorbent was evaluated by infrared spectral analysis coupled with pattern recognition techniques using Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR). The ATR-FTIR spectral analysis of the fungal biosorbent revealed changes in particular spectral bands emerging from functional groups of biomolecules. Possibly, these functional groups of biomolecules are active fungal biosorbent sites involved in the interaction with Pb2+ ions. Thus, the surface of the fungal biosorbent is attractive for the sorption of metal ions making the fungal biomass as an effective and efficient biosorbent for the removal of Pb2+ ions.

    (Springer, 2024) Arslan, Dilek Senol; Ertap, Hueseyin; Senol, Zeynep Mine; El Messaoudi, Noureddine; Mehmeti, Valbone
    The present paper focused on synthesizing a polyacrylamide-titanium dioxide (PAA@TiO2) nanocomposite using a cross-linking method with N, N & PRIME;-methylenebisacrylamide and then using this composite to eliminate crystal violet (CV) dye from water and to characterize the adsorbent by XRD, FT-IR, and SEM-EDX techniques. The characterization revealed that TiO2 nanoparticles dispersed homogeneously within the polymer matrix. The maximum amount of adsorption was about 38.9 mg g(-1) under the adsorbent dose of 5 g L-1, 500 mg L-1 CV dye concentration, and pH 6.9. The interaction between the CV molecule and the PAA@TiO2 nanocomposite surface was studied using Monte Carlo (MC) and molecular dynamics (MD) simulations. The negative value of the Eads (- 586.56 kcal mol(-1)) of the CV molecules onto the PAA@TiO2 nanocomposite surface gives credibility to the experimental results. All obtained results showed that PAA@TiO2 hybrid polymer nanocomposite could be an alternative adsorbent for crystal violet dye removal from wastewater.

    Recent advances in the removal of Sunset Yellow dye from wastewater: A review
    (Elsevier, 2024) Cigeroglu, Zeynep; El Messaoudi, Noureddine; Miyah, Youssef; Georgin, Jordana; Franco, Dison S. P.; Benjelloun, Mohammed; Senol, Zeynep Mine
    The present review focuses on the very latest development with respect to Sunset Yellow FCF (SY) removal from wastewater and dwells mostly on some of the most novel and efficient methods developed in response to everincreasing environmental and health concerns related to this widely used synthetic dye. In this work, adsorption techniques are criticized, considering that the high adsorption capacity of SY offers various environmental benefits. It lowers the concentration of wastewater, which means that fewer dyes are used in effluent processes. These advantages not only contribute to cleaner water bodies but also promote sustainable practices in the textile industry. This review considers in some detail the degradation of SY dye in advanced oxidation processes such as photocatalytic degradation, Fenton-like reactions, and ozonation with regard to general efficiency and cost pertinence. This review, along with biological treatments using isolated strains of bacteria and fungi capable of enzymatically degrading SY dye, offers an eco-friendly alternative against various available chemical methods. Hybrid systems in separation processes are often used for approaches consisting of multiple treatment processes, including biological, physical, and chemical, to completely treat water. For example, a particular treatment system may utilize both adsorption processes and incorporate some features of advanced oxidation treatment processes. This review aims to synthesize current literature and recent advancements to inform future research on SY removal, hence supporting sustainable wastewater treatment approaches and hybrid systems.
