摘要
采用活性炭纤维(ACF)阴极电芬顿和Ti/RuO_2-IrO_2(DSA)阳极间接氧化联用技术(EF-IE)对活性蓝19(RB19)染料废水进行降解研究,考察了不同反应条件对EF-IE联用技术处理RB19染料废水降解过程动力学的影响,并采用响应面优化法对运行条件进行优化。结果显示,当采用ACF+DSA时,RB19降解效果最好,降解过程符合准一级反应动力学模型;实验最佳条件是Fe^(2+)浓度0.92mmol/L,Cl-浓度12.14mmol/L,电流密度19.38mA/cm2。EI-IE联用技术是处理RB19的一种有效方法,通过响应面模型的研究,可以对EI-IE联用技术是处理RB19的结果进行预测。
Using activated carbon fiber （ACF） cathode Fenton and Ti/RuO2-IrO2 anode indirect oxidation （DSA） detection （EF-IE） of reactive blue 19 （RB19） dye wastewater degradation was studied, the different reac- tion conditions on the EF-IE detection processing RB19 dye wastewater degradation to the influence of process dy- namics, was examined and the response surface optimization method is used to optimize the operating conditions. Results show that when using ACF ＋ DSA, RB19 degradation effect is best, exact degradation process conforms to the first order reaction kinetics model; Experimental concentrations of FeE ＋ 0. 92 mM is the best condition, con- centration of Cl-12. 14 mM, current density of 19.38 mA/cm2. EI-IE coupling technique is an effective way to deal with RB19, through the study, the response surface model of EI-IE coupling technique is to predict the results of processing RB19.
