Problems of choosing metal-modifiers for graphite electrodes used in inversion voltammetry

Resumo

The problems of choosing metal-modifier for the surface of graphite electrodes used in voltammetric methods for analysis of a series of elements in solutions are reviewed. The presence of the modifier enhances the sensitivity of determination of elements using the graphite electrode, eliminates the impeding influence of some side processes, and makes it possible to determine elements having no electrooxidation peaks in the voltammograms in the working region of potentials of the graphite electrode.
