摘要

为探讨硫丹和联苯菊酯的辐照降解效果及茶叶中有效成分对两者降解的影响，利用60Co γ射线对硫丹和联苯菊酯的环己烷溶液进行辐照。研究了茶叶中茶多酚、咖啡碱、茶氨酸、维生素C等有效成分对硫丹和联苯菊酯辐射降解的影响。结果表明：同浓度的硫丹和联苯菊酯的辐射降解随吸收剂量的增加而增大，而在同一剂量下，硫丹的降解率随着浓度的增大而降低，联苯菊酯的降解却呈现先增加后降低的趋势；茶叶中的有效成分茶多酚、咖啡碱、茶氨酸及维生素C对硫丹的降解起促进作用，而茶多酚、咖啡碱及维生素C对联苯菊酯的降解起促进作用，茶氨酸则表现为抑制作用。

Abstract

The irradiation degradation of endosulfan and bifenthrin and the effect of tea components on the deg-radation were investigated. The γ-rays were used to study the effect of the irradiation on the degradation of endosulfan and bifenthrin in hexane solution meanwhile the effect of tea components, such as tea polyphenol, caffeine, theanine and vitamin C on the irradiation degradation of endosulfan and bifenthrin was also investigated. The results show that at the same concentration the irradiation degradation effects of endosulfan and bifenthrin can improved with absorbed doses, while at the same absorbed dose the irradiation degradation effects can decrease with increment of concentration for endosulfan, and can increase initially and then decrease for bifenthrin. Additionally, tea polyphenol, caffeine, theanine and vitamin C can promote the irradiation degradation of endosulfan, but only theanine can make irradiation degradation of bifenthrin worse.Cited
