| Abstract | ||
| 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 10-6–2.5 10-5 M with a correlation coefficient of more than 0.98. | ||
