FIELD: chemistry.
SUBSTANCE: invention is intended for electrochemical technology of obtaining diluted alkaline solutions of hydrogen peroxide, and can be used in sorption technologies of water purification and water preparation. Method of obtaining hydrogen peroxide by cathode reduction of oxygen in alkaline solutions with injection of oxygen-containing gas is realised in electrochemical cell, which includes anode department, provided with anode, and cathode department, provided with coal-graphite cathode. In the process of hydrogen oxide obtaining applied is catholyte, consisting of 1% NaOH + 0.1 g/l MgSO4 + 10-3 M C6H4(OH)2, when ozone-oxygen mixture is supplied to cathode.
EFFECT: invention makes it possible to considerably increase output in current of hydrogen peroxide, twice reduce energy consumption, reduce size and weight parameters of cathode.
