Using cobalt-2,2'-bipyridyl complex as template, molecularly imprinted polymer membranes with supporting membranes were synthesized through in-situ polymerization by UV irradiation. The membranes’ surface features were analyzed by scan electron micrography. The imprinted membranes exhibit selective permeation for template in certain cobalt(II) acetate solution through permeation binding experiment. Cation and anion effects on permeation amount of 2,2'-bipyridyl through the molecularly imprinted polymer membrane was investigated respectively. It will be helpful for the development of application of imprinted polymers in sensor device and continuous separation process.

Key words: molecularly imprinted technique, molecularly imprinted membrane, membrane permeation, 2,2'-bipyridyl, cobalt
