Abstract: A selective method has been developed for extraction and separation of Ce(IV) with the high molecular mass crosslinked poly(acrylic acid), coated on silanized silica gel. The coated materials act as stationary phase for the extraction. The structure and thermal stability of crosslinked poy(acrylic acid) has been elucidated with the help of FTIR and TGA. Ion exchange and breakthrough capacity of the exchanger have been measured. Surface morphology of the exchanger has been studied by SEM. Ce(IV) has been separated quantitatively from various synthetic mixtures containing metal ions commonly present in thorium and uranium ores, minerals and fission products. The developed method has been tested for some real samples. A plausible mechanism for Ce(IV) extraction and elution has been suggested.
