Sažetak

Makroporozni hidrofilni kopolimeri glicidilmetakrilata i etilenglikoldimetakrilata modifikovani različitim aminima poseduju izraženu efikasnost i selektivnost pri sorpciji plemenitih i teških metala iz vodenih rastvora. U ovom radu su sintetisani uzorci poli( GMA-co-EGDMA) sa različitom poroznošću i funkcionalizovani reakcijama sa etilendiaminom, dietilentriaminom i trietilentetraminom. Pri nekompetitivnim uslovima je, šaržnom metodom na sobnoj temperaturi, određena brzina sorpcije Cu(II) jona iz vodenih rastvora na četiri uzorka amino-funkcionalizovanog kopolimera, kao i uticaj pH. Pokazalo se da je sorpcija Cu(II) jona veoma brza, sa poluvremenom sorpcije ? 2 min, kao i da se sa povećanjem pH kapacitet sorpcije Cu(II) povećava i maksimalan je na ~pH 5.
