Abstract

PURPOSE:To prepare an aq. solution of hydrogen peroxide at any time by a simple method by performing electrolysis of an electrolyte soln. with using an insoluble anode and metal paradium cathode, and then introducing air into the electrolytic solution. CONSTITUTION:An electrolysis tank 1 is filled with an electrolytic solution 2 (tap water, industrial water, etc.) in which an insoluble anode 3 such as platinum, carbon, etc., and a cathode 4 comprising metal paradium or paradium alloy are immersed. By applying DC voltage between the anode 3 and cathode 4 through leads 6, 7, hydrogen ions are reduced on the cathode 4 to produce hydrogen and this hydrogen is stored in the cathode in a form of hydrogenated paradium. By introducing air into the electrolytic solution 2 with a pump 9 through a nozzle 8, the reaction of oxygen in air with hydrogenated paradium in the cathode 4 is effected to produce hydrogen peroxide, which easily dissolves in the electrolytic solution 2 and gives aq. hydrogen peroxide. Thereby, aq. hydrogen peroxide can easily be produced at any time.
