Sorption of noble metal compounds by cross-linked copolymer of 1-vinyl-1,2,4-triazole with acrylic acid

Abstract

Sorption properties with respect to noble metal compounds were examined for a new divinyl benzene cross-linked nitrogen-containing heterocyclic copolymer of 1-vinyl-1,2,4-triazole with acrylic acid. The sorption recovery of chloride complexes of Au(III), Pt(IV), Pd(II), and Ag(I), as well as of silver nitrate from acidic solutions was examined in relation to the nature and concentration of acids and the contact time between the phases.

Formation of Stable Paramagnetic Nanocomposites Containing Zero-Valence Silver and Copper in a Polymeric Matrix

“…The homopolymer poly-1-vinyl-1,2,4-triazole possesses complexing ability, high chemical and thermal stability, biocompatibility, sorption properties, polymer electrolyte membrane properties, , and high stabilizing ability at the formation of nanocomposites with metal nanoparticles. , As for the polyacrylonitrile, it has properties such as conductivity, heat resistance, and hydrophilicity . Complex features of poly-1-vinyl-1,2,4-triazole in combination with the properties of polyacrylonitrile allow us to obtain copolymers, where the mutual increase of useful individual properties is typical for the homopolymers.…”

“…Previously, we reported the successful synthesis of nanocomposites with a homogeneous narrow dispersed distribution of silver nanoparticles in the copolymer matrix of 1-vinyl-1,2,4-triazole with acrylonitrile . A high ability for complexation, nontoxicity, as well as chemical and thermal stability are characterized for these polymers. , …”

Strong Antimicrobial Activity of Highly Stable Nanocomposite Containing AgNPs Based on Water-Soluble Triazole-Sulfonate Copolymer

“…Consequently, the antimicrobial activity of the nanocomposite is due to the presence of nanosized narrowly dispersed AgNPs in the copolymer matrix. The results indicate a higher antimicrobial activity of the AgNPs nanocomposite in the poly(VT-co-Na-VSA) matrix compared to silver-containing nanocomposites based on the homopolymer of 1vinyl-1,2,4-triazole [20] and poly(VT-co-VP) [21] synthesized by us earlier.…”

“…and natural (cellulose, gelatin, etc.) exhibit high stabilizing activity in the formation of Ag-NPs [15,[19][20][21][22][23][24][25][26][27][28][29][30][31][32].…”

“…We have previously shown that copolymers of 1-vinyl-1,2,4-triazole, depending on the functional composition, possess valuable properties (hydrophilicity, thermal stability, complexing ability, chemical stability, biocompatibility, non-toxicity, etc.) and are capable of effectively stabilizing nanoparticles of various metals [20,21,33].…”
