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-H2O2,UV-O3,UV-TiO2 and visible-light photocatalytic decomposition with TiO2 were used to degradation of MTBE in water.
