中文摘要：

采用气液混合放电降解水溶液中的阿特拉津,考察了放电输出功率、溶液pH值和Fe^2＋浓度对阿特拉津降解的影响,并初步探讨了其降解动力学.结果表明,提高放电输出功率、降低溶液pH值均能提高阿特拉津的降解率.相同实验条件下,添加Fe^2＋显著提高了阿特拉津的降解率,在Fe^2＋添加量分别为0.2,0.6,2.0mmol·l^-1时,随着Fe^2＋浓度的升高阿特拉津的降解率也不断提高.阿特拉津在气液混合放电反应器中的降解符合一级反应动力学.阿特拉津降解过程中的中间产物主要通过以下4种途径产生∶脱烷基作用、烷基氧化作用、脱氯羟化作用和脱氯羟化-氧化作用.

英文摘要：

Degradation of Atrazine in aqueous solution was conducted in a gas-liquid hybrid discharge reactor. The effect of output power, pH value and Fe^2＋ concentration on the degradation efficiency of Atrazine was examined. The initial investigation on the degradation kinetics of atrazine was conducted. The results revealed that the degradation efficiency of Atrazine increased with increasing output power and decreasing pH value, respectively. Under the same experimental conditions, the degradation efficiency of Atrazine increased dramatically in increasing Fe^2＋ the presence concentration of Fe^2＋ Furthermore, the degradation efficiency of atrazine increased with at the concentration of 0. 2, 0. 6, by gas-liquid hybrid discharge fitted first-order reaction kinetics. The degradation intermediates of Atrazine were produced by dealkylation, alkylic-oxidation, dechlorination and dechlorination-oxidation processes.
