Electrochemical Study of Flumetralin with a Cyclic Renewable Silver Amalgam Film Electrode

Abstract

The electrochemical properties of flumetralin (FLM) were investigated using square wave stripping voltammetry (SWSV) at cyclic renewable silver amalgam film electrode (Hg(Ag)FE). Two cathodic signals of FLM were recorded at Hg(Ag)FE in Britton-Robinson buffer of pH 9.5. After optimization of SWSV parameters and pH of supporting electrolyte, the linearity of peak currents vs. concentrations of FLM was found in the range of 5×10-9 mol L-1 - 1×10-7 mol L-1 with a detection limit 6.43×10-10 mol L-1. The developed method has been applied for the quantitative analysis of FLM in spiked tap water.
