玻璃碳阴极电芬顿降解孔雀石绿研究

Degradation of malachite green wastewater by electro-Fenton with reticulated vitreous carbon cathode

采用玻璃碳作为阴极,Ti/RuO 2作为阳极,开展了电芬顿降解孔雀石绿染料废水的研究。研究了电解质浓度、氧气曝气量、电流、pH等条件对玻璃碳阴极电芬顿降解孔雀石绿的影响。结果表明:在pH=3.0、电解质浓度0.1 mol/L、氧气曝气量100 mL/min、电流强度30 mA条件下,初始浓度为200 mg/L的孔雀石绿经过60 min处理,降解率达到99.11%。

Using reticulated vitreous carbon and Ti/RuO 2 as the cathode and anode for the degradation of malachite green wastewater by electro-Fenton.The influences of the electrolyte concentration,the oxygen flux,current and the pH value on the wastewater degradation by the electro-Fenton with reticulated vitreous carbon cathode.The results show that:malachite green with the initial concentration of 200 mg/L treated 60 min,99.11%degradation rate was achieved under the condition of pH=3,the concentration of electrolyte was 0.1 mol/L,the oxygen bubbled rate was 100 mL/min and the current was 30 mA.
