研究了在硝酸根和亚硝酸根存在条件下,水环境中氯虫苯甲酰胺的光化学降解行为,探讨了不同浓度的硝酸根和亚硝酸根对氯虫苯甲酰胺光降解速率的影响。结果表明,在氙灯照射下,氯虫苯甲酰胺光解反应符合一级反应动力学规律。硝酸根和亚硝酸根存在时会抑制氯虫苯甲酰胺发生光降解。
The photochemical degradation behavior of chlorantraniliprole in aqueous environment in the presence of nitrate and nitrite was studied. The effects of different concentrations of nitrate and nitrite on the photodegradation rate of chlorantraniliprole were studied. The results showed that under xenon lamp irradiation, the photodegradation reaction of chlorantraniliprole conformed to the first-order reaction kinetics. The presence of nitrate and nitrite inhibits photodegradation of chlorantraniliprole.
