Results: the optimal concentrations of the supporting electrolyte used for the determination of lead and copper(II) ions from the
composition of cosmetics, the influence of the pH of the solution medium on the peak height during the analysis were studied,
and the optimal potentials for the determination of lead and copper (II) ions by the stripping voltampermetric method were
selected. On the basis of the above studies, a highly sensitive method was developed for stripping voltammetric determination of
lead and copper(II) ions from the composition of cosmetics using selective parameters. The developed method was used in the
analysis of various real samples.
