PRODUCTION OF AQUEOUS SOLUTION OF HYDROGEN PEROXIDE AND DEVICE THEREFOR

摘要

PURPOSE: To provide a method and a device capable of producing hydrogen peroxide effective for a water treatment on-site and eliminating the need of a transport, etc., of a starting material. CONSTITUTION: A seawater 1 being a starting material is supplied to the first electrolytic cell 4 to electrolytically produce an alkaline aq. soln. and an acidic salt water, and an electrolysis of water is executed at the second electrolytic cell 7 while supplying the obtained alkaline aq. soln. and an oxygen-containing gas to produce the alkaline aq. soln. containing hydrogen peroxide. The obtained hydrogen peroxide-containing alkaline aq. soln. is mixed with the acidic salt water at need at a mixing tank 9 to obtain a neutral aq. sol. of hydrogen peroxide.
