초록

과산화수소의 발생은 일반적으로 유기 산화제를 포함한 산업적 프로세스의 넓은 분야에 응용된다. 과산화수소는 펄프와 제지 공업의 기계적, 화학적 처리를 위하여 사용되고 염소를 기초로 둔 화학제품에 알칼리 처리로 사용된다. 본 연구에서는 Nafiom과 러시아 양이온 교환막인 MK-40, 제조된 SPEEK막을 가스확산전극이 포함된 과산화수소 발생용 전해 셀에서 비교 실험한다. 다른 양성자 교환막에 효과에 따른 과산화수소 발생의 전기화학적 셀의 전압과 전류 효율, 에너지 소모를 연구한다.

There is great interest in the applicability of generated hydrogen peroxide to a variety of industrial processes, usually involving oxidation of organics. Hydrogen peroxide is now employed for the bleaching as well as mechanical and chemical treatment in the pulp and paper industries. It addition, it is considered as an agent to displace the traditional alkaline treatments with chlorine-based chemicals. This paper reports a comparative study of $H_2O_2$ electogeneration on gas-diffusion electrode in divided cell with several $Nafion^{(R)}$ proton-exchange membranes, Russian cation-exchange membrane MK-40 and SPEEK membrane. The influence of different PEMs on electro-chemical cell voltage, current efficiency and energy consumption of hydrogen peroxide generation has been studied.
