Chemical Synthesis and Characterization

ABSTRACT In this study, a chalcone derivative (BrBP‐Ch), designed as a small molecule adsorbent, was evaluated for the removal of Congo red (CR) dye from aqueous solutions. The adsorbent was characterized using FTIR‐ATR, 1 H NMR, 13 C NMR, HRMS (Q‐TOF), SEM, XRD, and zeta potential. Optimal conditions were determined…

This study investigates the synthesis and characterization of Fe₃O₄ nanoparticles coated with 3-aminopropyltriethoxysilane (APTES) and 4-dimethylaminobenzaldehyde (4-DMAB), aimed at their application in the adsorption of Pb(II) ions from aqueous solutions. The characterization of the Fe3O4@APTES@4-DMAB nanomaterial wa…

The extensive release of synthetic dyes into aquatic environments raises significant environmental and health concerns, particularly for Congo red, a highly soluble and toxic anionic azo dye. Addressing this issue requires the development of adsorbent materials that combine high efficiency with cost-effectiveness and…

, while additive presence further prolonged ACP stability, with citrate exerting a stronger effect than BSA. These variations were linked to differences in pH evolution, transient supersaturation, and solution speciation established during precursor mixing. Our findings highlight in situ potentiometric measurements as…

Three novel cadmium(II)-based coordination polymers, namely [Cd(H2O)3L]n·2nDMF·nH2O (1), [Cd(DMF)(H2O)L]n·nDMF (2) and [Cd2(4,4'-bpy)(H2O)4L2]n·2nH2O (3), were successfully synthesized under solvothermal conditions using the custom-designed organic linker 5-((thiophen-2-ylmethyl)amino)isophthalic acid (H2L). Structura…

The cyclodextrin (CD) oligosaccharides derived materials, e.g., p(α-CD), p(β-CD), and p(γ-CD) microgels were used in Li + ion adsorption studies, which revealed 55.4 ± 3.9, 85.1 ± 3.8, and 117.8 ± 4.9 mg Li+/g, respectively, in 12 h from 500 mg/L 100 mL aqueous solutions. The Li+ ion adsorption by p(CD)-based microgel…

Abstract Effective management of radioactive nuclear waste is vital for a sustainable energy supply. However, challenges in the synthesis and design of ideal adsorbent materials with desired adsorption properties remain. Here, a novel graphitic carbon nitride-based adsorbent was developed for the removal of uranium(VI…

In parallel with the increasing human population, industry is growing rapidly, which also causes an increase in the amount of wastewater. Dyes, which represent the largest group of pollutants in wastewater, are utilized in various industries, mainly in the textile sector. In addition to the annual production of tons o…

In this study, the removal of cationic dyes from synthetic wastewater by batch-mode biosorption processes was investigated using Equisetum palustre as a biosorbent.

In this study, the selectivity of the compound S,S'-di(2-pyridinyl)-2,2'-dithiodibenzothioate from media containing a mixture of metal ions was investigated using competitive liquid-liquid ion pair extraction, and its metal removal properties were studied in real water matrices. Extraction experiments conducted with s…
