Electroreduction at solid electrode materials and voltammetric determination of potassium hydrogenperoxomonosulfate

Abstract

The electrochemical behaviour of potassium hydrogenperoxomonosulfate (KHSO5) at carbositall and Au, Ag electrodes using the square-wave voltammetry (SWV) with 0.2 mol L–1 KHSO4 background solution (pH ~ 0.8) (Ep = 0.25 V vs Ag,AgCl/KСl(sat)) and differential pulse voltammetry (DPV) with 0.01 mol L–1 Na2 SO4+8×10–3 Н2SO4 background solution (pH = 0.9) (Ep = 0.14 V vs Ag,AgCl/KСl(sat)) correspondingly were studied. The voltammetric methods were developed and the possibility to determine the peroxomonosulfate in model solutions on the studied electrodes was shown.
