锰掺杂DSA电极及其对印染废水处理的过程优化
Mn-doped DSA electrode and optimized application in wastewater treatment process
摘要
Abstract
Ti/SnO2-Sb/SnO2-Sb-Mn electrode was prepared and characterized.The results showed that the intermediate layer played a great role in the electrochemical performance.The box-behnken model was used to optimize the electrochemical degradation of dye wastewater.The effect of electrolytic voltage,stirring rate and electrode span on degradation rate was quantitatively analyzed.A predictive model was established based on the degradation rate as the response value.The analysis showed that the selected mathematical model was well fitted,the influence factors followed the order:electrolytic voltage＞electrode span＞stirring rate.The optimum conditions were 4.8V,320r/min,1.5cm,and the predicted degradation rate could reach 99.3%.The predicted value of the model was close to the experimental data which illustrated the feasibility and effectiveness of the proposal method.This study could provide the technical guidance for the treatment of dyeing wastewater by electrocatalysis degradation.关键词
