甲基叔丁基醚(methyl tertiary butyl ether,MTBE)作为汽油添加剂被广泛使用后,MTBE通过多种途径进入水体,由于其降解缓慢,导致水体污染问题已受到广泛关注.因此,如何经济有效地去除水体中MTBE已成为人们普遍关注的热点.该文主要就消除环境有机污染物的光催化降解技术,特别是UV.Fenton、UV-H_2O_2、UV-O_3、UV-TiO_2及可见光下TiO_2等光催化技术应用于降解水体中MTBE的研究现状进行了综述.“,”The methyl tertiary butyl ether (MTBE),as an addictive in gasoline, is used widely since the leaded gasoline has been prohibited. By some ways, MTBE can be transferred into water. Since the degradation of MTBE is very slow naturally, the pollution of MTBE in water is attracting more and more attentions. How to remove the MTBE economically and effectively has become a hot spot in common concern. In this paper, the species of photocatalytic degradation technique and the methods were reviewed including UV-Fenton, UV-H_2O_2, UV-O_3, UV-TiO_2 and visible-light photocatalytic decomposition with TiO_2 were used to degradation of MTBE in water.
