Abstract:

The chloramphenicol(CAP) molecule-imprinted polymer(MIP) of o-aminophenol(OAP) on Pt(CAP-MIP-OAP/Pt) electrode was prepared via an electrochemical polymerization method using OAP as the functional monomer and CAP as the template molecule. This preparation method is simple. The as-prepared membrane is uniform and stable. The performances and configurations of the CAP-MIP-OAP/Pt and MIP-OAP/Pt electrodes were investigated using scanning electron microscope(SEM) and electrochemical techniques. The results illustrated that the MIP-OAP/Pt electrode exhibited improved selectivity and sensitivity for the CAP detection. A linear region of the CAP detection is in the range of 4.33×10-8~3.09×10-6 mol/L. The detection limit is 2.5×10-8 mol/L. Therefore, the MIP-OAP/Pt electrode shows potential application for the enrichment and detection of CAP in the environmental water sample.
