UV/Fenton氧化降解水溶液中甲基叔丁基醚的试验研究

采用UV／Fenton技术对污染水体中的甲基叔丁基醚（MTBE）进行了氧化降解试验。结果表明，在室温条件下，当H2O2为10mmol／L，FC＋为2mmol／L，pH为2．4时，起始摩尔浓度为1mmol／L的MTBE在30min内可去除99％；结果还显示了MTBE的降解分两个阶段，第一阶段是在UV／Fe^2＋／H2O2下的快速降解，第二阶段由于Fe^2＋的大量消耗而降解相对较慢。

Degradation of methyl tert-butyl ether in aqueous solution by UV/Fenton

Degradation of MTBE in aqueous solution by UV/Fenton was investigated.It was found that under the conditions of 10 mmol/L H_(2)O_(2),2 mmol/L Fe~(2+),pH 2.4 and room temperature,and initial 1 mmol/L MTBE in aqueous solution,99% of MTBE could be reduced within 30min,with a two-stage reaction,i.e.,firstly decomposed rapidly due to UV/Fe~(2+)/H_(2)O_(2) reactionsand then somewhat less rapidly because of the sharp decrease of Fe~(2+).
