摘要：

The complexing - ultrafiltration proces provides an ability for selective separation or concentration of metals present in multicomponent aqueous salt solutions. The behaviour of the ultrafiltration membrane in the presence of polymer ligand and with the increase of its concentration is of particular interest. Polyvinylalcohol and model solutions of Cu, Ni and Co with concentration 10 mg/l and membranes type UF-25-PAN are used in the investigation. The following parameters affecting the complexing-ultrafiltration process are studied: the optimum metal-polymer ratio and adequate pH-range for stable complex formation.
