For the first time, a new method is described for the determination of scandium based on the cathodic adsorptive stripping of the scandium-alizarin red S complex onto a carbon paste electrode. The second-order derivative linear scan voltammograms of the complex are recorded by use of model JP-303 polarographic analyzer from 0.0 to -1.0 V (versus SCE). Optimum conditions are found to be: an acetic...
A novel new method is described for the determination of zirconium based on the cathodic adsorptive stripping of the mix-polynuclear complex of zirconium-calcium-alizarin red S (ARS) at a carbon paste electrode (CPE). The second-order derivative linear scan voltammograms of the adsorbed mix-polynuclear complex of zirconium-calcium-ARS are recorded by model JP-303 polarographic analyzer from +0.20...
