Abstract

Commercial polymer microfiltration membranes were surface-modified with a graft copolymer of a functional monomer and a crosslinker in the presence of a template (triazine-herbicide). As result, membranes covered with a thin layer of imprinted polymer (MIP) selective to the template were obtained. The influence of the polymerization conditions on membrane recognition properties was studied by membranes’ capability to adsorb the herbicide from aqueous solution. The MIP synthesis is possible in both organic solvents and water. The low thickness of the MIP-layer and the porous membrane structure enable the highly specific sorption of the template at very high filtration rates. The possibility to introduce specific binding sites into porous membranes opens a general way to design new high-performance affinity membranes with application such as solid phase extraction.
