摘要
Abstract
Using molecular imprinting method,the 1,3-dimethylxanthine(Theophylline,THO)molecular recognition membranes,containing AN segments as membrane formation sites and AA segments as functional sites,were prepared by the phase inversion technique.Here,THO was selected as a template molecule.The hydrogen bonding between AA segments and the THO templates was measured by FT-IR and NMR.The THO templates can be removed from the membrane through washing with acetic acid aqueous solution.The permeation of THO through the membranes is far more than that of 1,3,7-trimethylxanthine(Caffeine,CAF),which demonstrated the function of THO molecular recognition of the membrane.The results also show that the increase of the THO templates concentration in the cast solution caused an increase of THO amounts taken into the copolymer membrane.关键词
