Abstract
The electrochemical behavior of amitraz was studied at polished (p-AgSAE) and mercury meniscus modified (m-AgSAE) silver solid amalgam electrodes. The reaction mechanism was investigated using direct current voltammetry (DCV) and elimination voltammetry with linear scan (EVLS).
The optimum conditions for differential pulse adsorption stripping voltammetry (DPAdSV) determination of amitraz were found in Britton-Robinson (BR) buffer mixed with ethanol in a volume ration of 1:4. DPAdSV with optimized parameters was applied for determination of amitraz in analyzed solutions.
The limits of detection were calculated as 8.9 nmol L-1 (t(acc) = 20 s) for m-AgSAE and 0.168 mu mol L-1 (t(acc) = 20 s) for p-AgSAE. The proposed method was successfully applied for determination of this compound in real sample solutions.
