Batch and fixed-bed column adsorption of crystal violet and safranin by zero-valent iron (nZVI) and nZVI-modified S. cerevisiae
Guler, Ulker Asli; Kundakci, Ozge (DESALINATION PUBL, 2018)Batch and continuous studies were conducted to examine the adsorption and degradation of zero-valent iron (nZVI) and nZVI-modified S. cerevisiae (magnetic yeast) to remove crystal violet (CV) and safranin (SF) from synthetic ... -
Mono and binary component biosorption of Cu(II), Ni(II), and Methylene Blue onto raw and pretreated S. cerevisiae: equilibrium and kinetics
Guler, Ulker Asli; Sarioglu, Meltem (TAYLOR & FRANCIS INC, 2014)The mono and binary biosorption of Cu(II) ions, Ni(II) ions, and Methylene Blue dye onto raw and pretreated S. cerevisiae was investigated in a batch system. The biosorption mechanism was characterized by FT-IR, XRD, and ... -
Mono and simultaneous removal of crystal violet and safranin dyes from aqueous solutions by HDTMA-modified Spirulina sp.
Guler, Ulker Asli; Ersan, Mehtap; Tuncel, Eliza; Dugenci, Feride (INST CHEMICAL ENGINEERS, 2016)The process of mono and binary removal of crystal violet and safranin dyes by Spirulina sp. (blue-green algae) modified with cationic surfactant is evaluated. The surfactant used was hexadecyltrimethylammonium bromide ... -
REMOVAL OF TETRACYCLINE FROM AQUEOUS SOLUTIONS USING NANOSCALE ZERO VALENT IRON AND FUNCTIONAL PUMICE MODIFIED NANOSCALE ZERO VALENT IRON
Guler, Ulker Asli (VILNIUS GEDIMINAS TECH UNIV, 2017)Nanoscale zero valent iron (nZVI) and functional pumice modified nanoscale zero valent iron (P-nZVI) were successfully synthesized and used for the removal of tetracycline (TC). These materials were characterized by SEM, ... -
Removal of tetracycline from wastewater using pumice stone: equilibrium, kinetic and thermodynamic studies
Guler, Ulker Asli; Sarioglu, Meltem (BIOMED CENTRAL LTD, 2014)In this study, pumice stone was used for the removal of tetracyline (TC) from aqueous solutions. It was characterized by XRD, FT-IR, SEM and BET analyses. Cation exchange capacity of pumice stone was found to be 9.9 meq/100 ... -
S. cerevisiae cells modified with nZVI: a novel magnetic biosorbent for nickel removal from aqueous solutions
Guler, Ulker Asli; Ersan, Mehtap (DESALINATION PUBL, 2016)The present study was conducted to evaluate the applicability of S. cerevisiae cells modified with nZVI (magnetic biosorbent) for the Ni(II) ions removal from aqueous solutions. This composite was synthesized in ethanol ... -
Synthesis of hydroxyapatite/clay and hydroxyapatite/pumice composites for tetracycline removal from aqueous solutions
Ersan, Mehtap; Guler, Ulker Asli; Acikel, Unsal; Sarioglu, Meltem (INST CHEMICAL ENGINEERS, 2015)Synthesized hydroxyapatite/clay (HA-C) and hydroxyapatite/pumice (HA-P) composites were used for tetracycline (TC) uptake studies from aqueous solution and their uptake capacities were compared. HA-C and HA-P composites ...
