Abstract
There is great interest in the applicability of generated hydrogen peroxide to a variety of industrial pro-cesses, usually involving oxidation of organics. Hydrogen peroxide is now employed for the bleaching as well asmechanical and chemical treatment in the pulp and paper industries. It addition, it is considered as an agent to dis-place the traditional alkaline treatments with chlorine-based chemicals. This paper reports a comparative study ofH2O2 electogeneration on gas-diffusion electrode in divided cell with several Nafionproton-exchange membranes,Russian cation-exchange membrane MK-40 and SPEK membrane. The influence of diferent PEMs on electro-chemical cell voltage, current efficiency and energy consumption of hydrogen peroxide generation has been studied.
