Square wave voltammetric method for the determination of substituted oxadiazol in aqueous solution

الملخص EN

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.
