Abstract

The voltammetric behavior of pesticide amitraz was investigated at polished silver solid amalgam electrode (p-AgSAE) and at mercury meniscus modified silver solid amalgam electrode (m-AgSAE) (inner diameter 0.5 mm). The results were compared with those obtained using hanging mercury drop electrode. The reaction mechanism was studied by direct current voltammetry and elimination voltammetry with linear scan. Optimum conditions for determination using differential pulse adsorption stripping voltammetry of this compound were found in Britton-Robinson buffer mixed with ethanol (4:1 v/v). The limits of detection were calculated as 8.9 × 10-9 mol dm-3 (with t acc = 20 s) for m-AgSAE and as 0.168 × 10-6 mol dm-3 (with t acc = 20 s) for p-AgSAE. The proposed method was successfully applied for determination of amitraz in real samples of river water.
