Abstract

A sensitive adsorptive stripping voltammetric method for the determination of simeton with universal buffer solution has been described. The method was based on the adsorption accumulation of simeton at a hanging mercury drop electrode. The overall reduction process is under controlled diffusion. The adsorptive peak was observed at −0.8 V vs SCE in acidic solution 2 < pH < 6. The peak response was characterized with respect to pH, accumulation potential, time, and scan rate. The calibration plot was found to be linear from 1.13 × 10 − 5 to 3.5 × 10 − 8 M with a limit of detection of 2.0 × 10 − 8 M. Finally, the method has been applied for the determination of simeton in its formulations and vegetable samples.
