电化学联用技术降解活性蓝19染料的研究

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。

Study on the degradation of Reactive Blue 19 effluent by integrated electro-chemical process

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 studies, examines the different reaction conditions on the EF - IE detection processing RB19 dye wastewater degradation process dynamics, the influence of 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 Fe2 + 0.92 mM is the best condition, concentration 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.
