Abstract: During the last ten years, the Electrochemical Engineering and Membrane Technology group of the Chemical Engineering Department at the University of Castilla-La Mancha (Spain) has worked on the treatment of water effluents contaminated with heavy-metal ions. The aim of this research line is the study of the stages of a heavy-metal selective recovery process, in which the concentration stage is carried out by polymer supported ultrafiltration (PSU). Amongst membrane technologies, polymer supported ultrafiltration is a technique used to separate metal ions from aqueous effluents. In this technique, the use of polymers is a key point as the first step of the process consists of a selective reaction between the target metal ions and a water-soluble polymer. These polymers should be chemically stable and should allow a strong and selective reaction with the metal ions of the target water.
