摘　　要：研究了模拟太阳光作用下γ-HCH在雪中的光转化动力学、影响因素、反应产物和机理。实验结果表明:γ-HCH的光转化符合一级动力学方程;H2O2和NO-2促进了γ-HCH的光转化,HCO-3抑制了γ-HCH的光转化,酸性条件抑制了γ-HCH的光转化而碱性条件无影响。γ-HCH光转化的主要途径是还原脱氯。The photoconversion kinetics of γ-HCH, influence factors, photoconversion products and mechanism in snow were studied under the simulated sunlight. The results showed that the photoconversion of γ-HCH obeyed the first-order kinetics equation; H2O2 and NO2- promoted the photoconversion of γ-HCH; HCO3- had inhibited effect;acidic condition showed inhibition while alkaline condition had no effect. The photoconversion mechanism of γ-HCH was reductive dechlorination.
