DSA类阳极催化氧化降解有机污染物的机理初探

FIRST EXPLORATION OF MECHANISM OF DEGRADATION OF ORGANIC POLLUTANTS BY DSA ANODE CATALYTIC OXIDATION

电解催化氧化技术是一种新兴的氧化技术。本文采用 DSA类阳极的方法对电解催化降解有机污染物的机理进行了研究 ,表明在电解过程中能够产生氧化能力极强的 OH·自由基 。

Electrolytic catalysis oxidation method is one of AOT(Advanced Oxidation Technologies), which are developed newly abroad. An simple and convenient detecting means of OH· radicals and DSA(Dimensionally Stable Anodes)--typed anodes, made by ourselves with special technology, is employed in this study. The results show that a mass of OH· radicals, with very high oxidation ability, can be produced during electrolysis. They can oxide the organic pollutants in the wastwater, i e the pollutants are degraded in an indiret way, which is the main mechanism of electrolytic catalysis oxidation technology. In view of the reasons mentioned above, the technology is one of AOT.
