Hydrated zirconium dioxide (HZD) is an amphoteric sorbent, acting as an anion-exchanger in acid solutions and a cation-exchanger in alkaline. The purpose of this work was to study the sorption activity of (HZD) with respect to palladium(II) in solutions of PdSO/sub 4/ x 3H/sub 2/O in sulfuric or perchloric acids. It was shown that HZD can extract cationic palladium(II) aqua complexes selectively and rapidly from weakly acidic solutions. The sorbed aqua complexes of Pd(II) undergo conversions with formation of hydroxo complexes in the sorbent phase.
