Abstract: A novel voltammetric sensor for O,O-dimethyl-(2,4-dichlorophenoxyacetoxyl)(3'-nitrophenyl)methinephosphonate (Phi-NO2) based on molecularly imprinted polymer (MIP) film electrode is constructed by using sol-gel technology. The sensor responds linearly to Phi-NO2 over the concentration range of 2.0 x 10-5 to 1.0 x 10-8 mol L-1 and the detection limit is 1.0 x 10-9 mol L-1 (S/N = 3). This sensor provides an efficient way for eliminating interferences from coexisting substances in the solution. The high sensitivity, selectivity and stability of the sensor demonstrates its practical application for a simple and rapid determination of Phi-NO2 in cabbage samples
