摘要
目前对电解催化降解有机污染物的机理存有争议。本文用苯酚作为 HO·的捕集剂 ,采用高效液相色谱法对形稳阳极电解处理有机废水的机理进行了研究 ,表明在电解过程中产生了对苯二酚和邻苯二酚等羟基化产物 ,这正是HO·和芳环类化合物之间的特征反应。实验结果说明电解催化体系能够产生氧化能力极强的 HO· ,可以氧化降解废水中的有机污染物 ,即有机污染物以间接氧化的方式降解 ,这是电解催化氧化技术的主要机理。由于上述原因 。
There are disagreements on the mechanism of organics degradation using electrolytic catalytic method.In this paper,high performance liquid chromatograph was employed to study the organics degradation mechanism in electrolytic catalytic system,with Phenol used as the collector of HO·.The results showed hydroquinone and catechol had been produced during the electrolysis,those hydroxylation products were the ones of the characteristic reaction between HO· and aromatic compounds.The experimental data indicated HO· could been produced during electrolysis,whose oxidation ability was very high.They could oxide the organic pollutants in the wastewater,i.e. the pollutants are degraded in an indirect way,which was the main mechanism of electrolytic catalytic method.Because of mentioned above,the electrolysis catalysis oxidation technology was one of AOT/P (advanced oxidation technologies/processes).
