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 ...
Novel amide- and imide-co-polymers modified with sulfathiazole as efficient chelator for selective extraction, pre-concentration and determination of trace inorganic antimony (as Sb(III)) from edible vegetable oils by ultrasound assisted-cloud point extraction coupled to micro-volume UV-spectrophotometry
(Elsevier, Available )
The study described the synthesis, characterization, and application of newly prepared sulfathiazole-modified amide/imide co-polymers for the extraction of trace Sb(III) from edible vegetable oils. The method was based on ...
A pH-dependent CT sensitive method for detection of trace Mn in milk by UV-spectrophotometry
(Elsevier, Available )
In this study, a new method was developed for the extractive pre-concentration/detection of trace Mn in milk prior to analysis by UV-spectrophotometry. The method is based on the pH-controlled intra-ligand charge transfer ...
A new pre-concentration procedure based on poly(styrene-co-maleamide and imide) copolymers modified with 2-hydrazinobenzothiazole prior to spectrophotometric monitoring of inorganic as (as As(III)) in edible vegetable oils
(Elsevier, 27 Decembe)
This study describes the development of 2-hydrazinobenzothiazole modified-amide/imide co-polymers for the extraction/pre-concentration of trace As(III), from edible vegetable oils. Their characterization was realized by ...
