Complexation aided ultrafiltration (CAUF) is an attractive separation process for the removal of trace toxic elements from
effluents at low pressures. Freshly prepared polysulfone, polyamide, polyamide hydrazide and polyvinyl butyral blended cellulose
acetate membranes are studied with respect to the separation behavior for radioactive cerium tracer in the presence of polyethyleneimine.
The effect of polymer loading and pH of the feed system are investigated.
