Abstract
Novel methods of decreasing the concentration of hydroxyl ions in an electrochemically generated alkaline peroxide aqueous solution consisting of partial neutralization of a stabilized solution of alkaline hydrogen peroxide, electrodialysis, and dialysis of an aqueous solution of alkaline hydrogen peroxide. The methods of the invention can be performed at ambient temperature and pressure.
