| 摘要: |
| 为探索一种降解阿特拉津的新型有效方法,以Sb掺杂钛基SnO2电极为阳极,不锈钢板为阴极,采用电催化氧化技术对阿特拉津废水进行降解,研究不同影响因素对阿特拉津降解效果的影响,并分析阿特拉津的降解途径.结果表明:当电流密度为200 A/m2、阿特拉津初始质量浓度为10 mg/L、溶液pH值为6.97、反应30 min后,阿特拉津去除率达100%,此时能耗仅为6.67×10-2kWh/g.阿特拉津的电催化氧化降解过程主要为脱烷基、脱氯-羟基化、烷基氧化等反应,伴随着阿特拉津的降解,生成OHA、DAA、ANE等一系列中间产物.电催化氧化方法可经济、有效地去除水中阿特拉津. |

| Abstract: |
| To find a new effective method of degradation of atrazine,the degradation was studied by electrocatalytic oxidation of atrazine in water,and Sb doped Ti/SnO2 electrode was used as anode and stainless steel plate as cathode.The main influencing factors and degradation pathway of atrazine were discussed.Results showed that when current density was 200 A/m2,initial concentration of atrazine was 10 mg/L and pH value was 6.97,100% atrazine was removed within 30 min.Meanwhile,power consumption was only 6.67×10-2 kWh/g.The primary degradation process is dealkylation,dechlorinationa and alkylic-oxidation,and a series of intermediate products such as OHA,DAA,ANE were produced during the process of electrocatalytic oxidation of atrazine.The results suggest that electrocatalytic oxidation method can be cost-effective removal atrazine. |
