Abstract: In Calix [6] arene as a functional monomer, based on the sol - gel and molecular imprinting technique, prepared O, O- dimethyl group - (2,4-dichlorophenoxy acetyl) (3'-nitrophenyl) methylene phosphonate (f-NO2) molecular imprinting electrochemical sensors, and using a variety of testing methods of the study electrode reaction behavior of the sensor, given the possible reaction mechanism under optimized experimental conditions, the concentration of organic voltammetric reduction peak current and phosphonate 1.0 × 10-8 ~ 2.0 × 10-5 mol / L in the range a good linear relationship (r = 0.998 3), the detection limit of 1.0 × 10-9 mol / L. This sensor is used to determine the cabbage samples phosphonate recovery with satisfactory results.
