The insoluble R-HgS salt (where R is the bupirimate frame excluding sulfur) formed on the static hanging mercury drop electrode (SHMDE) was electrochemically reduced by giving a fairly well defined cathodic peak within the pH range of 1.0 to 8.0. The peak potentials (E (p)) were shifted toward more negative values with increasing pH, and a maximum peak response appeared at -1320 mV (vs. Ag/AgCl) at a pH 6.0. The calibration plot was a straight line in the range of 0.013 to 9.43 mg L-1. The detection limit at pH 6.0 was measured as 4.0 mu g L-1 under the conditions of E (acc) = -700 mV and t (acc) = 10 s. The validity of the recommended method was assessed from the recoveries of spiked tap water, natural peach juice, and commercial peach juice.eninfo:eu-repo/semantics/closedAccessBupirimateFungicideDeterminationVoltammetryMercury electrodeArticleQ3Q2222269276WOS:000369016200014
