A Voltammetric Technique Using A Modified Carbon Paste Electrode for the Determination of Aclonifen

Abstract

A method for the determination of aclonifen at a carbon paste electrode modified with tricresyl phosphate has been developed. The optimum electrochemical regime proved to be differential pulse voltammetry (DPV) in the negative potential range from-200 to-1600 mV. The optimum pH for the determination proved to be pH = 8. The calibration dependence is linear and the limit of detection achieved for the method was 2·10-6 mol/dm3. The method is fast, reliable and it is suitable for the detection of aclonifen in the concentration range from 2·10-6 to 1·10-4 mol/dm3.
