摘要

Metallothionein (MT) imprinted TiO_2 membrane was synthesized via surface sol-gel process, using MT as template and TiO_2 sol as imprinted matrix. Appropriate template cavities in the TiO_2 sol-gel membrane were formed after the template molecules were removed on treatment with 1% NaOH solution. In situ technique of quartz crystal microbalance (QCM) was employed to study the molecular imprinting behavior of MT on nanocrystalline titania membranes. The imprinted membrane showed selectivity recognition for MT as compared to the other proteins. The amount of adsorption increased with the increasing of MT concentration both on imprinted membrane and non-imprinted membrane. The adsorption amount increased with the increasing of pH on imprinted membrane.
