Square Wave Voltammetric Method for the Determination of Substituted Oxadiazol in Aqueous Solution

A rapid, sensitive and accurate method for the determination of substituted oxadiazol (I&II) has been developed based on the reduction of electroactive group (-C=S) at hanging mercury electrode by using square wave voltammetric technique. The reduction peaks obtained at 0.028 and 0.172 V Vs Ag/AgC1 fir compounds I & II respectively at pH 2 in Britton Robinson buffer are recommended for the trace determination of these compounds. Regression analysis on standard curve indicated a linear relationship between peak current and concentration over the rang 1.2 10-62.5 10-5 M with a correlation coefficient of more than 0.98.
