| 摘 要： | 研究了臭氧活性炭与光催化联用降解饮用水中邻苯二甲酸二(2-乙基己)酯(DEHP)。当使用臭氧浓度为2.0mg/L、活性炭负载TiO_2催化剂浓度为0.02g/g、pH值10.0时,对DEHP含量为12.04mg/L的饮用水光催化降解6h,DEHP的去除率可达99.5%。研究结果表明,臭氧活性炭与光催化联用可有效去除水中邻苯二甲酸二(2-乙基己)酯。

| Abstract: | Degradation of di-(2-ethylhexyl)phthalate(DEHP)in drinking water was investigated using a combination method of ozone-active carbon and photocatalysis.Under the conditions of the ozone concentration of 2.0mg/L and TiO_3 catalyst loaded in the active carbon of 0.02g/g,the initial pH value of 10.0 and the DEHP concentration of 12.04mg/L,the photodegradation degree reached 99.5% after 6 hours of illumination.It can be concluded that DEHP in drinking water can effectively be degraded by this combined technique. |
