| Abstract: | Partial least squares (PLS) has been used to analyze synthetic o-, m-, p-dinitrobenzene mixtures using differential pulse voltammetry (DPV) at hanging mercury drop electrode (HMDE) in the present paper. The medium conditions including concentrations of chloric acid, potassium chloride, and ethanol have been investigated. In the solution of 0.1 mol/L HCl-0.2 mol/L KCl-20% ethanol satisfactory results for the analysis of the synthetic mixtures are obtained. The relative standard deviations are 4.69, 4.78 and 6.92% for o-, m-, and p-dinitrobenzene, respectively, for the determination of the synthetic mixtures. |
