Synthesized of a novel xanthate functionalized polypropylene as adsorbent for dispersive solid phase microextraction of caffeine using orbital shaker in mixed beverage matrices
(2022)
A newly synthesized xanthate functionalized chlorinated polypropylene (PP-Xa) was used as adsorbent for the orbital shaker based on dispersive solid phase microextraction (OS-DSPME) of caffein from several tea, coffee, ...
Assessment of arsenic in water, rice and honey samples using new and green vortex-assisted liquid phase microextraction procedure based on deep eutectic solvent: Multivariate study
(2022)
The aim of present study was to determine the arsenic in water, honey and rice samples using a new and green vortex-assisted liquid phase microextraction (VA-LPME), which is based on deep eutectic solvent (DES) by hydride ...
Chemometric approach for the spectrophotometric determination of chloramphenicol in various food matrices: Using natural deep eutectic solvents
(2022)
A novel, simple and green temperature controlled-natural deep eutectic solvent emulsification liquid–liquid microextraction (TC-NADES-LLME) coupled with UV–vis spectrophotometry was optimized for preconcentration and ...
Calculations of the magnitude of responsivities in pH-, temperature- and ion- responsive hydrogels
(ELSEVIER, RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, JUN 2022)
Stimuli-responsive hydrogels (SRHs) were prepared by thermal free radical redox polymerization in the aqueous solution of N-isopropyl acrylamide (NIPAAm), acrylamide (AAm) with any weak organic acid (such as propenoic acid, ...
An evaluation on S-type adsorption isotherm in the model of crosslinked polyhydroxamates/oxazine dyes/water interactions
(SPRINGER, ONE NEW YORK PLAZA, SUITE 4600 , NEW YORK, NY 10004, UNITED STATES, AUG 2022)
The efects of crosslinker and dye type on swelling and S-type adsorption properties of crosslinked polyhydroxamates (CHP)
were investigated. CHPs containing N,Nʹ-methylenebisacrylamide (N), or ethylene glycol dimethacrylate ...
Calculations of the magnitude of responsivities in pH-, temperature- and ion- responsive hydrogels
(ELSEVIER, RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, JUN 2022)
Stimuli-responsive hydrogels (SRHs) were prepared by thermal free radical redox polymerization in the aqueous solution of N-isopropyl acrylamide (NIPAAm), acrylamide (AAm) with any weak organic acid (such as propenoic acid, ...
Selective Removal of Mercury(II) Using Hydrogels Prepared by Gamma Radiation
(LVIV POLYTECH NATL UNIV12, LVIV, LVIV OBLAST 79000, UKRAINE, 2022)
To selectively remove mercury(II), 2-hydroxy-ethyl methacrylate (HM) and 2-hydroxyethyl methacrylate/acrylamide (HM/ACR) hydrogels were synthesized using radiation. These hydrogels were used in swelling, diffusion, and ...
An indirect method for the analysis of bisphenol A, as a Mn(III)–chelate complex, in milk samples by ultrasound assisted-cloud point extraction/flame atomic absorption spectrometry
(The Royal Society of Chemistry, 06.07.2022)
A method for indirect determination of bisphenol A (BPA), as a Mn(III)–chelate complex, in milk samples by
flame atomic absorption spectrometry (FAAS) was developed. The method was based on cloud point
extraction with ...
Lignin grafted hydroxyapatite entrapped in polyacrylamide: Characterization and adsorptive features for Th4+ and bovine serum albumin
(Elsevier, 2022)
Water-soluble sulfolignin (SL) was grafted onto hydroxyapatite (Hap) by using epichlorohydrin. SLgHap was then entrapped in cross-linked polyacrylamide by in situ polymerizations of acrylamide and N, N′ -methylenebisacrylamide ...
The design of push-pull substituted coronene molecules for optoelectronic applications
(Elseiver, 01.06.2023)
The optoelectronic and electronic properties of coronene ([6]circulene) and push-pull coronene molecules were predicted by using different computational chemistry programs. For this aim, the electron/hole reorganization ...
