Differential pulse adsorptive stripping voltammetry of fenitrothion on a polysiloxane modified graphite paste electrode
Keywords: polysiloxane modified electrode, stripping voltammetry, fenitrothion
AbstractThe preparation and characterization of a graphite paste electrode modified with silicone OV-101 (a polysiloxane stationary phase material used in gas chromatographic columns) is described. The potential use of the modified electrode for preconcentration and detection offenitrothion, an organophosphate pesticide, was studied using differential pulse adsorptive stripping voltammetry. Under optimum experimental conditions a detection limit for fenitrothion of 7 ppb can be achieved using a 10-min accumulation time with relative standard deviation of 4% for n = 3.
