Abstract

Active composite polymeric membranes were prepared in order to improve the lifetime of supported liquid membranes (SLM) for the separation of Nd(III). The aim of the paper was to demonstrate the applicability of these type of composite membranes, based on two layer of polysulfone (PSf) and polyamide (PA), for metal transport. Thus, the membrane characterization, the influence of the carrier concentration in the transport, and the stability of the membranes have been studied. The results obtained are quite satisfactory, both from the standpoint of transport ability and stability. The need for an efficient carrier has been demonstrated and its influence reported. In addition, a preliminary investigation of the transport mechanism has been performed.
