摘要：

A mixed matrix of chitosan (CTS) and poly(vinylidene fluoride) (PVDF) was used to fabricate a novel composite membrane (CTS(Cd2+)/PVDF) via a one-step film-forming process that employs Cd2+- imprinted technology. The membrane was then applied for the selective removal of Cd2+ from aqueous solution. Surface functional groups and morphologies of prepared membranes were characterized. Cd2+ adsorption properties and mechanical tensile strengths of the membranes were investigated. Results showed that the CTS(Cd2+)/PVDF membrane exhibited high Cd2+ adsorption capacity, excellent mechanical tensile strength, and good adsorption selectivity toward Cd2+ in the presence of Pb2+.
