Zusammenfassung:A new ion-exchange resin was obtained by incorporating a tripropylamine group into a tamarind polysaccharide resin (TTA). The TTA resin was characterized by FTIR, elemental analysis, and other physicochemical properties. The influence of pH, treatment time and resin concentration on the adsorption of metal ions from industrial wastewater was investigated. It was found that the obtained TTA resin effectively removes heavy metal ions in the following order: [Fe.sup.2+] > [Cu.sup.2+] > [Zn.sup.2+] > [Cd.sup.2+]> [Pb.sup.2+]. Keywords: industrial wastewater, tamarind, tripropylamine, ion-exchange resin, adsorption, flocculants. Nowa zywice jonowymienna otrzymano poprzez wbudowanie grupy tripropyloaminowej do zywicy polisacharydowej tamaryndowca (TTA). Zywice TTA scharakteryzowano za pomoca FTIR, analizy elementarnej i innych wlasciwosci fizykochemicznych. Zbadano wplyw pH, czasu obrobki i stezenia zywicy na adsorpcje jonow metali ze sciekow przemyslowych. Stwierdzono, ze zywica TTA skutecznie usuwa jony metali ciezkich w nastepujacej kolejnosci: [Fe.sup.2+]>[Cu.sup.2+]>[Zn.sup.2+]>[Cd.sup.2+]>[Pb.sup.2+]. Slowa kluczowe: scieki przemyslowe, tamaryndowiec, tripropyloamina, zywica jonowymienna, adsorpcja, flokulanty.
