Abstract

Liquid—liquid extraction of divalent palladium by solutions of the hexachloroderivate of cobalt dicarbolide (HBCl6) in the mixture of solvents (30 v/v % nitrobenzene+20 v/v % n-dodecane +50 v/v/ % toluene) from nitric acid medium has been studied. Besides HBCl6 the organic phase contained also 2,2′-dipyridyl (dipy). The yield of palladium extraction from 0.5M HNO3 is greater than 99.0%. The species extracted into the organic phase corresponds to the formula [Pd(dipy)2] (BCl6)2.
