A sensitive, fast and low-cost molecular imprinted polymeric sensor for quantitative determination of parathion was prepared with chitosan（CS） as function matrix and parathion（PT） as template molecule via constant potential electrochemical deposition. Sensitive response was obtained with a detection limit of 1.0× 10-7 mol/L and an excellent recognition for PT was achieved due to the good memory capacity of the sensor. The developed sensor exhibited good fabrication reproducibility and acceptable stability, which provided a new promising tool for pesticide analysis.
