| 摘 要： | 以300 W高压汞灯为光源,研究了不同类型、不同浓度的农用表面活性剂对氯虫苯甲酰胺在水溶液中光降解行为的影响。结果表明,农乳500表现为轻微的光猝灭效应;低浓度时,随着表面活性剂十八烷基三甲基氯化铵(OTAC)浓度的增大,氯虫苯甲酰胺的光解速率逐渐增大,但当表面活性剂浓度增大到25 mg/L时,产生光猝灭效应;Tween-80对氯虫苯甲酰胺光解的影响最大,当浓度为5 mg/L、10 mg/L和25 mg/L时,光敏化率分别为16.74%、29.52%和43.17%;自制的混合表面活性剂能促进氯虫苯甲酰胺的光解。表面活性剂对氯虫苯甲酰胺在水溶液中光降解行为的影响受表面活性剂类型和剂量的影响。 |

| Abstract: | The impacts of surfactants on the photolysis of chlorantraniliprole in aqueous solutions were investigated using 300 Whighpressure mercury lamp as light source.The results indicated that Nongru500 had slight photoquenching effect on chlorantraniliprole.With the increase of the concentration of octadecyl trimethyl ammonium chloride(OTAC),the photolysis speed of chlorantraniliprole gradually increased at low dosage,however,at higher dosage(25 mg/L) the surfactant displayed photoquenching effect.Tween80 posed the biggest effect on the photolysis of chlorantraniliprole.The photosensitive rates of Tween 80 with the spiking concentrations of 5 mg/L,10 mg/L and 25 mg/L were 16.74%,29.52% and 43.17%,respectively.The self-made mixed surfactant facilitated the photolysis of chlorantraniliprole.The results suggested that the photolysis of chlorantraniliprole in water was affected by the type and dosage of the surfactants. |
