Preparation, characterization, and adsorption properties for metal ions of a novel chelating resin containing sulfoxide and diethylene glycol

Abstract

A novel chelating resin containing sulfoxide and diethylene glycol, poly{4-vinylbenzyl-[2-2-(hydroxyethyl)ethoxyl]sulfoxide} (PVESO) was synthesized using chloromethylated polystyrene (PS-Cl) as material. Its structure was characterized by elemental analysis, infrared spectra, and scanning electron microscopy (SEM at different temperatures was also investigated. The results showed that the adsorption rate was governed by film diffusion at 208C and 258C, by particle diffusion at 308C and 358C.

Synthesis, characterization, and properties for Hg2+ of new chelating resin containing sulfoxide and 3‐aminopyridine

“…12,13 The adsorption properties of the resins containing sulfide, sulfone, and sulfoxide for metal ions have been reported in the literatures. 14,15 It has been shown that the resin with sulfoxide presents a high capacity and good selectivity toward noble and heavy metal ions.…”

Selective complexation and extraction of Ag(i) and Zn(ii) versus Pb(ii) by polymer beads modified by attachment of a bipyridyl–calixarene-based chelate

“…Various functional polymers have been studied for this purpose. For silver, lead and zinc, Merrifield resins bearing chelating groups such as sulfoxide and/or heterocycles, sulfoxide and diethylene glycol, sulfur and polyamine [4][5][6][7][8][9][10] have been used. Thiosemicarbazide-formaldehyde resins have also been prepared.…”

Synthesis and Characterization of Novel Poly(sulfoxide-urethane)s from 2,2'-Sulfoxidebis(4-methyl phenol) with Various Diisocyanates

“…Recently, chelating resins bearing sulfoxide groups have been utilized in separating noble metal, poisonous mercury, rare earth and radioactive element uranium from aqueous solutions [17].…”
