Abstract

A separation process for gallium, from the leaching solution of a zinc refinery residue, using a liquid surfactant membrane with 2-bromodecanoic acid as the carrier was studied experimentally to investigate the effect of dilution of the feed solution on the extraction rate of gallium. It is found that the extraction rate has a maximum value at a certain degree of dilution. A simple rate model in which outer water phase film diffusion, interfacial chemical reaction and membrane phase diffusion are taken into account, is proposed to explain the mechanism.
