Abstract
Voltammetric behavior of triasulfuron (TS), sulfonylurea herbicide, was investigated using mercury meniscus modified silver solid amalgam electrode (m-AgSAE) and hanging mercury drop electrode (HMDE). It was found that TS provided one well-developed reduction peak and the highest current response was recorded in Britton-Robinson buffer of pH 3 (m-AgSAE) and 2.5 (HMDE), respectively. Differential-pulse voltammetry (DPV) with optimized working parameters was applied for analysis of model solutions containing TS with good sensitivity (LD(m-AgSAE) = 6.4 Ã 10â8 mol Lâ1 and LD(HMDE) = 2.7 Ã 10â9 mol Lâ1, respectively). Proposed method was successfully applied in analysis of herbicide preparation and river water.
