The interaction between MT and AA was expressed by infrared spectra, the functional groups of -SH in MT had lone pair electrons, which could formπ-πwith -C=O in AA. The equilibrium binding experiment and Scatchard analysis showed, at least three kinds of binding sites would exist when MT-imprinted polymer formed, the most adsorption capacities were 3.3896mg/g, 0.9362mg/g, 1.6583mg/g respectively; most terminal thiolate sulfurs in MT were polymerized as binding sites in the process of polymerization, which could observed from TEM, binding capability of other thiolate sulfurs was weak since spatial hindrance existed.
