Adsorption of Ce(IV) Anionic Nitrato Complexes onto Anion Exchangers and Its Application for Ce(IV) Separation from Rare Earths(III)

Ce(IV) nitrato complexes were adsorbed on two anion exchangers based on polyvinyl pyridine (PVP) and quaternized PVP incorporated into porous silica matrix. The effect of nitric acid concentration (0.5∼6 mol·L −1) and temperature (278∼318 K) on Ce(IV) sorption efficiency was investigated. Sorption i...
