摘要
以Pb/PbO_2为工作电极以CoSO_4为催化剂,利用电生羟基自由基对中性红、罗丹明B、碱性品红等3种有机染料进行了降解。并且研究了电解电位、 pH值、温度等因素对染料降解脱色的影响。结果表明,脱色率接近100%,COD去除率达90%以上。实验证明反应符合一级反应动力学模式,实验还测定了动力学参数。
Electro-generated hydroxyl radical was used to degrade neutral red, rhodamine B and alkaline fuch sine with Pb/PbO2 as electrode and CoSO4 as ca -talysis. The affected factors of electrolysis potential, pH value, temperature etc. in dyes'degrading and decolorizing have been studied. The results showed that the decolorizing rate was near 100% and COD removal rate was above 90%. The experiments proved that the reaction according with grade I reactive kinetic mode, and kinetic parameters were also determined.
