     this paper describes a novel technology for the reuse of electronic wastewater by advanced oxidation process (aop) using an fe/al-immobilized catalyst. the metal catalyst in the aop improved the oxidation of low-molecular-weight organic compounds, such as acetone and isopropylalcohol, in electronic wastewater. the removal efficiency of acetone and isopropylalcohol were 78.5% and 99.9%, respectively. the optimal combination of metal catalysts in the oxidation of acetone was fe and al—10% al in various fe/al catalysts. the optimal ph was less than 3, and the proper addition of h2o2and catalysts was an important factor in the aop. using optimal metal catalysts, significant amounts of organic compounds were removed from raw electronic wastewater using a continuous flow reactor. we conclude that an aop with a metal catalyst removes low-molecular-weight organic compounds (91% removal efficiency of isopropylalcohol) and can be implemented as a wastewater treatment and reuse system.
