Abstract: A sensitive electrochemical sensor for the detection of parathion based on molecularly imprinted polymer of organic-inorganic hybrid sol-gel from PTMOS and chitosan onto glass electrode was constructed. The sensor exhibited good selectivity and sensitivity to parahtion.The procedure of forming recognition cavity and sensitivity to parathion on the imprinted electrode were demonstrated. A highly linear response to parathion in the concentration range of 3×10-7~1×10-4 mol/L was observed, with a detection limit of 1×10-7 mol/L (S/N=3). Parathion imprinted and nonimprinted polymer films were exposed to a series of closely related compounds and the sensor exhibited good selectivity and sensitivity to parathion.
