Sažetak

Umreženi makroporozni kopolimer glicidilmetakrilata i etilenglikoldimetakrilata, poli(GMA-co-EGDMA), sintetizovan je suspenzionom kopolimerizacijom a zatim funkcionalizovan reakcijom bočnih epoksidnih grupa sa etilendiaminom. Pri statičkim uslovima je ispitana selektivnost, kapacitet i brzina sorpcije teških i plemenitih metala iz vodenih rastvora pomoću aminofunkcionalizovanog poli(GMA-co-EGDMA)-en. Sorpcija Ni(ll), Cu(ll) i Zn(ll) jona ispitana je pri dinamičkim uslovima, propuštanjem rastvora za galvanizaciju kroz kolonu napunjenu makroporoznim poli(GMA-co-EGDMA)-en. Regeneraciona moć kopolimera i sposobnost njegove ponovne upotrebe procenjena je na osnovu eksperimenata četiri uzastopna ciklusa sorpcije i desorpcije jona metala.
