【摘要】 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10 mmol/L,Fe2+为2 mmol/L,pH为2.4时,起始摩尔浓度为1 mmol/L的MTBE在30 min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/Fe2+/H2O2下的快速降解,第二阶段由于Fe2+的大量消耗而降解相对较慢。更多还原

【Abstract】 Degradation of MTBE in aqueous solution by UV/Fenton was investigated.It was found that under the conditions of 10 mmol/L H₂O₂,2 mmol/L Fe²⁺,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/Fe²⁺/H₂O₂ reactionsand then somewhat less rapidly because of the sharp decrease of Fe²⁺.更多还原
