    Abstract

    The stripping of palladium by thiourea, which was extracted with didodecylmono-thiophosphoric acid, was carried out using a stirred transfer cell. The dependency of the stripping rate on the concentration of the chemical species was examined and the stripping mechanism was investigated. Measurements of inter facial adsorption equilibrium of the extractant and the palladium complex were also conducted. It was found that the extractant and the palladium complex had an interfacial activity. A model of interfacial reaction accompanying the reaction in an organic phase was proposed, and the experimental results were quantitatively explained by the model.
