Synthesis of platinum ion imprinted polymer and applications in electronic wastes

A novel platinum (IV) ion-printed polymer was synthesized containing 1- (2-aminophenyl) pyrrole, methacryloyl chloride and 4-Vinylpyridine groups. Copolymer of poly (pyrrolobenzomethacrylamide-co-4-vinylpyridine-co-divinylbenzene) (Pt-PVD) synthesized in two steps was characterized by FT-IR and elemental analysis and SEM images were taken for surface morphology. The synthesized polymer was used as an adsorbent in platinum enrichment and optimum experimental conditions were determined. The platinum analysis was performed with ICP-MS. Optimum conditions is pH: 4, eluent flow rate: 1 mL.min-1, sample flow rate: 1 mL.min-1, eluent type: 1M HCl: 1% thiourea, eluent volume: 250 mL for Pt-PVD imprinted polymer. Detection limit, enrichment factor and adsorption capacity of method were found to be 22.45 μg.L-1, 12.5 and 20.50 mg.g-1 respectively. The developed method that synthesized Pt (IV) ion-imprinted polymer was applied mobile phone (Nokia 3310) and computer card samples.
