摘要：
Molecularly imprinted polymers (MIP), as functional polymers, have the ability to selectively recognize template molecules and have been widely used in various fields. Vanillin (VAN), an important taste component in food, can be found in the seeds of the tropical flower orchid. Based on the benefits of MIP and membrane separation technology, vanillin imprinted blend membrane was successfully created utilizing VAN as template molecule. MIP was employed for electrode modification to perform highly sensitive detection of VAN. The mechanics of imprinting, elution and electrode regeneration were explored. The adsorption behavior of vanillin on electrode was examined. Under optimal conditions, the MIP based electrochemical sensor can perform linear detection of VAN at 1x10(-11)-1x10(-4) M. The detection limit is 5 x 10(-1)(2) M.
