Abstract: An electrochemical sensor based on electropolymerized molecularly imprinted polymers(MIPs) for diethylstilbestrol(DES) detection is reported. The sensor was prepared by electropolymerizing o-phenylenediamine(OPD) on a glassy carbon electrode in the presence of template diethylstilbestrol. Template can be quickly removed by 50% (volume fraction) ethanol-water solution. The analytical performance of the molecularly imprinted polymer was studied and indirect analytical method based on the medium of potassium ferricyanide was established. A linear relationship between the concentration of DES and relative peak current change of potassium ferricyanide was obtained with a range from 1.0 x 10(-7) to 5.1 x 10(-6) mol/L. The result shows that this sensor provides an efficient way for eliminating interferences from compounds with similar structures to that of DES
