Research on Catalytic Degradation of Organic Wastewater Using CoFeMgO Non Homogeneous Fenton

Abstract

Methyl orange stimulated wastewater was treated using non-homogeneous Fenton reaction. First the effect of catalyst composition on the treatment was investigated and then further investigation of the impact of reaction conditions on the degradation effect in the catalytic process was carried out. It showed the optimal conditions of treating methyl orange wastewater(100ml) of 10mg/L, The optimal conditions for catalyst preparation through experiments above were: proportion of the elements in the catalyst was Co0.5Fel.0(MgO)2.5, this article examined the impact of reaction conditions on the catalytic properties of the catalytic process. It turned out that on the condition that the amount of catalyst was 0.9g/L hydrogen peroxide concentration was 2.5ml/L, within the scope of application in a wide pH (4~14), catalyst degradation efficiency was significantly superior to conventional homogeneous Fenton system and methyl orange removal efficiency was above 95%.
