负载Ni炭气凝胶粒子电极电催化氧化处理甲基橙废水的研究
Study on electro-catalytic oxidation treatment of methyl orange wastewaters with Ni-carbon aerogels electrodes
摘要
Abstract
Carbon aerogels doped with and without metal Ni were synthesized by sol-gel polymerization of a mixture of resorcinol and formaldehyde, followed by gelation and ambient pressure drying and carbonization in N2 gas atmosphere. The treatment process of simulated methyl orange wastewaters using carbon aerogels as particle electrode in a three-dimensional electrolysis reactor was studied. Factors affecting the removal efficiency were investigated, such as electrolysis time, voltage, electrode dose and particle electrodes types. The results showed that the Ni-modified carbon aerogels can improve distinctly its pore volume and specific surface area and enhance greatly capability of electro-catalytic oxidation treatment to methyl orange wastewater. Under the optimal conditions of electro-catalytic oxidation treatment, the removal efficiency of the initial methyl orange concentration and chemical oxygen demand (COD) could arrive at 98.9％ and 95.1％ , respectively.关键词
