| 摘 要： | 利用O3/H2O2降解莠去津,对氧化产物进行了色谱分析,以评价该体系降解莠去津效能.莠去津初始浓度2 mg/L,7.5mg/L的O3单独氧化去除率为27.2%;相同O3投量下,H2O2/O3摩尔比0.75时,5 min莠去津的去除率最高可达96.5%,表明H2O2/O3体系对莠去津的去除效果良好,降解速度快.以离子色谱对产物的离子进行分析,莠去津浓度下降的同时,硝酸根和氯离子浓度增高.GC-MS检测的产物和对LC-MS谱图的分析表明,有机产物中存在脱乙基、脱异丙基和脱氯莠去津,说明H2O2/O3并不能彻底氧化莠去津,因此工程中作为主要去除单元或突发性污染事件的应急手段可能还需要与活性炭等单元联用.

| Abstract: | The endocrine disrupter Atrazine was oxidized by O_3/H_2O_2 system and the products were analyzed to assess the degradation efficiency of Atrazine.When it's initial content was 2 mg/L and O_3 dosage was 7.5 mg/L,Atrazine was removed about 27.2% after 5 minutes.Under the same condition,H_2O_2/O_3 molar ratio was 0.75,Atrazine maximum removal rate reached 96.5%,which suggested that Atrazine could be degraded by O_3/H_2O_2 system effectively.Ion Chromatography(IC) analysis showed that concentrations of chlorid... |
