Abstract
In this study, chelating ion exchangers containing phosphonic (-PO(OH) (2)) acid groups (RSPO, Diaion-CRP200) and the new chelating resins (D iphonix) containing sulfonic and gem-diphosphonic acid groups chemical ly bonded in a styrene-divinylbenzene polymeric network have been inve stigated for sorption of Cd(II) ions from phosphoric acid solutions. C omparison of acid dependencies of Cd(II) uptake measured with that obt ained using a commercial sulfonic acid type ion-exchange resin (Dowex 50W(X8)) and a solvent containing resins (Actinide-CU) has been perfor med. The resin Diphonix has been employed for columnar sorption of Cd( II) and Cr(III) ions from phosphoric acid solutions.
