| 摘 要： | 考察了在玫瑰红(RB)存在下γ-六氯环己烷(γ-HCH)在冰中的光降解. 结果表明, 光敏剂RB通过其激发态RB]*及其产生的1加速了γ-HCH的光降解, RB浓度是影响光降解率最显著的因素; γ-HCH在较低初始浓度下的光敏化降解更快; 无机盐离子的种类和浓度可以改变冰表面上类液层(LLL)的比例从而影响γ-HCH的光解. 通过分析γ-HCH光降解产物提出了RB存在时冰中γ-HCH的光降解作用机理.

| Abstract: | Rose bengal(RB)-sensitized photolysis of gamma-hexachlorocyclohexane(γ-HCH) in ice was investigated. The results show that the photosensitizer RB accelerate the photolysis of γ-HCH by the excited state RB]* and its product singlet oxygen(1), and RB concentration is the most significant factor affecting the photolysis rate; the sensitized photolysis of γ-HCH at lower initial concentrations on the μg/L scale is faster; the type and concentration of inorganic salts can change the proportion of liquid like layer(LLL) on the surface of ice and thus affect the photolysis of γ-HCH. Based on the results above, the photoproducts were analyzed and the sensitized photolysis mechanism of γ-HCH in the presence of RB was proposed. |
