Abstract
1,2,3-Triazole-group-containing resins for palladium ion adsorption in HCl media were prepared. The monomer, synthesized from acryloyl chloride and 3-(1,2,3-triazol-1-yl) propanol, and a crosslinker, ethylene glycol dimethacrylate, was polymerized in dimethyl sulfoxide via radical polymerization. The specific surface area decreased with increasing monomer:crosslinker molar ratio. In acidic media, the adsorption of palladium ions was greater than those of platinum and ruthenium ions, because stable complexes were formed between palladium ions and triazole groups. The maximum amount of palladium ions adsorbed was 0.41 mol/kg.
