Determination of 5-nitrobenzimidazole using HMDE and AgSE in the presence of surfactants

Abstract

Optimal conditions were found for the determination of 5-nitrobenzimidazole by differential pulse voltammetry on hanging mercury drop electrode and polished silver solid amalgam electrode using surfactants Tritone X-100, cetyltrimethylamonium bromide and sodium dodecylsulphate in the concentration range 1×10-4 to 1×10-7 mol/l as signal enhancers.
