Abstract
Concentrations of hydrogen peroxide in dynamic (flowing) electrolytes and suspension systems have been determined using the methods of potentiometric redox-titration and cyclic voltammetry. The quantitative determination of H2O2 up to concentration ≈ 10–6 M was shown to be possible by using microelectrodes polarized in the convective diffusion mode, while employing the voltammetry, and using the mathematical processing of results of micropotentiometric titration. The effect of hydrophobicity of the reactor surface on the resulting concentration of H2O2 has been detected that should be taken into account during the microanalysis.
