In a study of the electrochemistry of peroxide in the leaching of metals and minerals it has been confirmed that the measured potentials of solutions (hydroxide, carbonate, bicarbonate and ammonia) containing peroxide on platinum and mineral electrodes are not true equilibrium potentials but mixed potentials established by simultaneous oxidation of peroxide to oxygen and reduction to water. The potentials are dependent only on the solution pH and not on the nature of the surface or the solution. A mixed-potential model has been derived that is consistent with the potential measurements.
