Differential Pulse Polarographic Method for the Determination of Thiophanate-Methyl in its Fungicide Formulation (Topsin M) and Agricultural Produces

Chetan Chauhan [2] | D K Sharma | Berhe Akele


Abstract: The voltammetric behaviour of the thiophanate-methyl in its fungicide formulation (Topsin M) and agricultural produces has been studied in the presence of surfactant, Triton-X-100 in acetonirile medium at dropping mercury electrode (DME) by differential pulse polarography (DPP). The proposed DPP method based on the investigation that the electrochemical response of thiophanate-methyl facilitated in presence of Triton X -100 (0.1 %V/V) at the DME electrode surface in term of enhanced peak current as well as sharpening of diffused controlled peak at 140 mV (vs SCE). The method has successfully been applied to both commercial fungicide formulation and agricultural produces. Recoveries of the active ingredient from formulation analysis and fortified agricultural produces samples (wheat, rice and apple
