Abstract
The method validation of chemical analysis for triphenyltin(IV) p-hydroxybenzoate compound by squarewave voltammetry has been performed. This compound has successfully been synthesized, fully characterized and applied as anticorrosion inhibitor. The squarewave voltammetry was chosen as this method has excellent sensitivity and the chemical analysis was easily conducted. The validation parameters used were linearity, limit of detection, precision and sensitivity, for this purpose the measurements of standard solution of triphenyltin(IV)phydroxybenzoate prepared were varied its concentrations. The concentrations used were 1.6 x 10-4 M; 3.2 x 10-4 M; 4.8 x 10-4 M; 6.4 x 10-4 M; and 8.0 x 10-4 M. The measurements were set at conditions of potential windows of +700 mV to +1,400 mV, scan rate potential of 100 mV/s, working electrode Au, auxiliary electrode Pt, reference electrode Ag and supporting electrolyte used was NaCl solution 0.02 M in H2O-DMSO (3 : 1). The results showed that the method validation analysis gave regression linear equation of ip= 6.1857C + 7.945, coefficient correlation (r) 0.995128, standard deviation percentage (%RSD) 1.96%, limit of detection (LoD) 0.099 mM and sensitivity (S) 6.1857 μA/mM
