A Voltammetric Technique Using A Modified Carbon Paste Electrode For The Determination Of Aclonifen

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.
