Multielement analysis in stripping voltammetry

An original software that allows different versions of stripping voltammetry to be used in domestic Khan-2 and VA-03 computer-controlled analyzers is tested. An increase in the number of metal ions to be determined in a sample by stripping voltammetry to five or more components is exemplified by the determination of the components of the Cd(II)-Pb(II)-Cu(II) model system in the proposed supporting electrolyte (NH₄Cl, pH 2–4) at a gradiently formed mercury-graphite electrode. These conditions provide the stability of a droplet mercury coating of the electrode, a change in the potentials of the group deposition of the components, and the optimization of the analytical signals. The analytical potential of the specified approaches are estimated by determining the number of components in the control and real-water samples using different methods.
