Voltammetric determination of selected pesticides at a meniscus modified silver solid amalgam electrode
2010
Abstract
Voltammetric determinations of dinitroaniline based pesticides Benfluralin, Butralin, Dinitramine, Fluchloralin, and Trifluralin were developed using differential pulse voltammetry (DPV), and square wave voltammetry (SWV) at a meniscus modified silver solid amalgam electrode (m-AgSAE). Optimal conditions were found for their determination in the concentration range 1.10-4 - 1.10-6 mol.l-1 of each pesticide in mixture of Britton-Robinson buffer and methanol in ratio 1:1.
The applicability of the newly developed methods was verified by direct determination of testyed pesticides in ground water matrix.
