Abstract:Recovery of acids from hydrometallurgy industrial spent liquors via membrane- dialysis is a feasible method. The waste acids performance in anion-exchange membrane and the application of diffusion dialysis in hydrometallurgy were introduced. The prospect of diffusion dialysis technology was also inducted.
Key words: diffusion dialysis; anion-exchange membrane; waste acid liquor; recovery
