The solvent extraction of zinc chloride from aqueous hydrochloric acid solution with Amberlite LA-2, a long-chain secondary alkylamine, dissolved in n-hexane was carried out at 30°C by the single drop method. The extraction rate mechanism was fairly well explained by the Handlos-Baron model, taking account of the interfacial reaction at the drop surface as a rate-determining step.Furthermore, it was found that the diffusion of zinc around a droplet is very rapid compared both to that inside a droplet and to the interfacial reaction under this experimental condition. Zinc in the continuous phase is extracted into the dispersed phase as a neutral species, ZnCl2.
