本实验以250mL烧杯为反应器,阴极为石墨电极,阳极为钛基IrO2电极[10],之所以采用Ti/rO2电极是因为IrO2是一种活性很高且非常稳定的氧化物,IrO2涂层可大大延长电极寿命,同时可以降低析氯电位,增大析氧电位.阴阳两极的表面积均为20cm2,长宽分别为10cm、2cm,厚度可忽略不计,浸入溶液长度为8cm,未浸入长度为2cm,从而电极的有效面积为32cm2（正反两面）,电极的工作电流由直流稳压电源提供,反应过程中采用磁力搅拌器进行搅拌,实验装置图如图1所示.
本实验以钛基IrO2电极作阳极,石墨作阴极,电极间距3cm,NaCl为支持电解质,在外加电场存在下分别对三种模拟染料废水进行电解实验研究.在温度20±2℃条件下,分别考察了pH值、电压、电解时间、NaCl投加量对染料（三种染料结构式见图2、图3、图4）废水脱色率及COD去除效果的影响.分别用蒸馏水配制三种染料溶液500mg/L,取已配好溶液200mL,固定三个因素,改变待研究因素,分别测定反应后的溶液色度和COD,并绘出相应的去除率曲线,以此评价染料降解效果.
在pH=3、电压20V、NaCl投加量2.5g/L的条件下,不同电解时间对染料去除效果的影响见图5.电解氧化处理时间直接影响到染料的脱色率及COD去除率,氧化时间越长,通过的电量越多,脱色率及COD去除率明显提高；对于活性橙X-GN和活性黄X-R,电解30min后染料溶液的脱色率几乎达到100%,此时COD的去除率仅有53%,对处理30min后的溶液继续电解,当处理60min后COD去除率已达到68%；对于活性黑KN-B,电解60min后染料溶液的脱色率达到100%,COD去除率达到60%.继续延长反应的时间,发现COD去除率几乎不再提升.因为随着反应的不断进行,有机物浓度逐渐降低,电流效率逐渐下降,因此,最佳电解时间为60min.

中文第一句写的就有问题：“以250mL烧杯为反应器,阴极为石墨电极,阳极为钛基IrO2电极[10].”没有对应关系.应该是“以250mL烧杯为反应器,石墨电极为阴极,钛基IrO2电极[10]为阳极.”[10]是要注释的地方吧,我也不一一说明了,反正在英文里都认真的对照了文法.比如英文翻译的第二句：按传统的语法规则,The reason…is because…句型是错误的,because 应改为 that 才对.如:Wrong:The reason I was not there is because I was out of town.Right:The reason I was not there is that I was out of town.然而笔者在阅读英美报刊时却遇到了 The reason…because…句型.实际上这种句型近年来在口语中用得颇多.但是我还是按照经典的翻译方法翻译.不过中文里有疑问的地方就没有太较真.
In this experiment,use a 250mL beaker as reactor,graphite as cathode ,and the titanium-based IrO2 electrode [10] as the anode ,the reason for adopting Ti/rO2 electrode is that IrO2 is a highly active and very stable oxide,IrO2 coating electrode life can be greatly extended,while reducing chlorine evolution potential,increasing the oxygen evolution potential.The surface area of the cathode and anode are both 20cm2,length and width are 10cm,2cm,respectively,thickness can be ignored,the length submerged in the solution is 8cm,the length above the solution is 2cm,and thus the effective electrode area is 32cm2 (both sides),the Operating Current of the electrode is supplied by the DC power,during the reaction using a magnetic stirrer to stir ,the experimental device shown in Figure 1.
In this study,use titanium-based IrO2 electrode as the anode,graphite as cathode (electrode spacing is 3cm) NaCl as the supporting electrolyte,in the presence of external electric field do electrolysis experimental research on the three kinds of simulated dye wastewater .In temperature conditions 20 ± 2 ℃,investigated the impact of pH,voltage,electrolysis time,NaCl addition amount on the dyes (three dyes structure shown in Figure 2,Figure 3,Figure 4) decolorization rate and COD removal efficiency.Use distilled water to prepare three kinds of dyes solution 500mg / L,with 200mL solution has been obtained,fixed the three factors,changes the factors to be studied,then measure color and COD of the solution after the reaction,and draw the corresponding removal rate curve in order to evaluated the dye degradation.
In the conditions pH = 3,Voltage 20V,2.5g / L NaCl dosage ,the impact of different electrolysis time on the removal of dyes shown in Figure 5.Electrolytic oxidation time directly affects the decolorization rate and COD removal,the longer the oxidation time,the more electricity passed by,and the decolorization rate and COD removal significantly improved; for active orange X-GN and active yellow XR,after electrolyzing 30min the dye solution decolorization rate is almost up to 100%,while the COD removal efficiency is only 53% ,Continue to electrolyze the solution which has been handled 30min,after 60min treatment the COD remova has reached 68%; for Reactive Black KN -B,after electrolyzing 60min the dye solution decolorization rate comes to 100%,COD removal rate to 60%.Continue to extend the reaction time,COD removal rate was found almost no raise.Because as the reaction going,organic matter concentration decreased,current efficiency gradually decreased,therefore,the best electrolysis time is 60min.
