Abstract
Abstract A novel voltammetric sensor for O , O -dimethyl-(2,4-dichlorophenoxyacetoxyl)(3′-nitrophenyl)methinephosphonate (Phi-NO 2 ) based on molecularly imprinted polymer (MIP) film electrode is constructed by using sol–gel technology. The sensor responds linearly to Phi-NO 2 over the concentration range of 2.0 × 10 −5 to 1.0 × 10 −8 mol L −1 and the detection limit is 1.0 × 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-NO 2 in cabbage samples.
