Abstract
The process is characterized by using metallic membrane as a filter which is charged by a separate DC-power supply and it may become experimentally very effective in increasing the separation potency and migration flux. The technique of integrating migration with electromembrane was evaluated for the removal of chromium. The transport was found to be adequately described by an equation in which the rate is proportional to the chromium concentration. The rate of dichromate ions transported across the membranes and the gel water content of membrane increased when the ratio of electromembrane potential and cell system potential was increased. The back diffusion of dichromate ions through the membrane due to concentration gradient was considered negligible in this work.
