Abstract: Voltammetric behavior of triasulfuron (TS), which belongs to sulfonylurea herbicide family, was studied using two working electrodes: mercury meniscus modified silver solid amalgam electrode (m-AgSAE) and hanging mercury drop electrode (HMDE) for comparison. It was found that TS provided one reduction peak on both used working electrodes. The highest response was observed in the environment of Britton-Robinson buffer (BR) of pH 3 (m-AgSAE) and 2.5 (HMDE), respectively. Working parameters of differential-pulse voltammetry (DPV) were optimized and this method was applied in analysis of agricultural formula and river water.
