According to the calculations, in the presence of equimolar concentrations of uranyl‐ion and hydrogen peroxide at 5 < pH < 7, the predominant species is UO 2 O 2 0complex. Spectro‐photometrically, it has been confirmed in the bulk of the solution giving the apparent concentration stability constant K = 2 × 10 5 mol −1 L. Electrochemically, normal, differential pulse polarography and cyclic voltammetry at DME and HMDE are used to elucidate the reduction scheme of the uranyl‐monoperoxo complex.
