Adsorption properties of amine modified lignin-hydrogel composite for uranyl ions: Theoretical and experimental insights
(2023)
A new modified material was synthesized and characterized as ethylene diamine modified (EA) Polyacrylamide (PAA)-Lignin (L). The adsorption features of EA modified PAA-L were studied for uranyl ions. The characterization ...
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 ...

Determination of trace cobalt (II) in spices samples by ultrasonic assisted cloud point extraction with spectrophotometry
(JOURNAL OF MOLECULAR STRUCTURE, 2023)
In this study, ultrasonic assisted cloud point extraction (UA-CPE) method was developed for the determination of Cobalt (II) (Co(II)) in spices. After extraction and preconcentration, the Co(II) contents of the samples ...

Analysis of boronic acids containing amino ferrocene by DFT approach and in silico studies
(Elsevier, 2023)
The synthesized (2)-(6) complexes and (2′)-(6′) hypothetical complexes formed by attached boranic acid esters were optimized at the DFT-B3LYP/GEN level. The structural and spectroscopic properties (IR, 1HNMR , 13CNMR ) of ...
