Abstract

A new molecularly imprinted polymer (MIP) has been synthesized using 1-naphthylamine as the template molecule. Equilibrium adsorption and selectivity adsorption experiments showed that the molecularly imprinted polymer has better binding ability and higher selectivity for 1-naphthylamine, comparing to non-imprinted polymer (NIP). The molecularly imprinted solid phase extraction (MI-SPE) was prepared by using the molecularly imprinted polymer as sorbent and used to extract and pre-concentrate 1-naphthylamine, 2-naphthylamine, 3-aminobiphenyl and 4-aminobiphenyl from the mainstream tobacco smoke. Compared to non-imprinted solid phase extraction (NI-SPE), MI-SPE can effective to extract selectively the four Hoffmann aromatic amines from the mainstream tobacco smoke under the optimized conditions.
