SYNTHESIS AND ION-EXCHANGE BEHAVIOR OF A NEW 3-COMPONENT ION-EXCHANGEMATERIAL - ZIRCONIUM(IV) ARSENATE VANADATE

Zirconium(IV) arsenate vanadate was prepared by adding a mixture compr ising 0.05 M sodium hydrogen arsenate and 0.05 M sodium metavanadate t o an aqueous solution of zirconium(IV) dichloride oxide (0.05 M) in di fferent volume ratios at pH 1. The material possessed a good ion-excha nge capacity of 1.20 and 1.30 meq g(-1) of exchanger for the Na+ and K + ion, respectively, and was fairly stable in dilute mineral acids, bu t insoluble in water, acetic acid, formic acid, ethanol, and 1,4-dioxa ne. The distribution coefficients of a large number of metal ions were determined in different solvent systems.
