Abstract

The copper electrode modified by clay has been utilized for the determination of pesticides with high sensitivity based on their redox behavior. The experiment is performed on the use of cyclic and square wave voltammetry. Square wave voltammetric response showed a linear calibration curve in the range 10-3 to 10-7mol.L-1.
