Abstract: The novel molecularly imprinted polymer which has specific recognition ability to ethyl carbamate (EC) was prepared by taking β-cyclodextrin derivatives as functional monomer and ethyl carbamate as template molecular by molecular imprinting technology(MIT). The compositions and structure were characterized by IR, 13C-NMR and SEM. The selective recognition ability of the molecularly imprinted polymer to EC was determined by GC-MS, and the theoretical equations of Scatchard were first established using the non-linear fitting method. The experimental results showed that the synthetic reaction route designed is reasonable and the molecularly imprinted polymer to EC is prepared successfully. The molecularly imprinted polymer to EC produces molecular recognition effect to EC through the interaction of molecular co-valent bond, which has the excellent selective adsorption ability to EC. The quantitative analysis by theoretical equation show that the molecularly imprinted polymer has two types of recognition sites to the template molecular, and the dynamic theoretical equation reflects its excellent adsorption characteristics. The relevant results can provide beneficial reference for the removal and separation of carbamate pollutants with no specific structure
