| 摘 要： | 为寻求一种能有效降解毒死蜱残留的技术方法，本文采用60Co γ射线辐照水溶液和芦笋中的毒死蜱，并对比了毒死蜱的辐照降解率。结果表明，辐照剂量在0～12kGy时，水溶液中毒死蜱的降解率随剂量的增加而增大，4kGy的辐照可使其降解率达95.5%；芦笋中毒死蜱的辐照降解率偏低，8kGy辐照时降解率最高，达到30.0%。进一步研究表明，芦笋成分Vc、芦丁和总糖等的存在对辐照降解毒死蜱有抑制效应。

| Abstract: | In order to seek an effective technique to degradate chlorpyrifos residue, chlorpyrifos water solution and asparagus containing chlorpyrifos as testing material s were irradiated by 60Coγ-ray and their degradation rate were determined and compared The results showed that the degradation rate increases with irradiation dose in the ranfe of 0 and 12kGy, and it reaches 95.5% at 4kGy. The degradation rate of chlorpyrifos in asparagus is low and comes to the maximum of 30.0% when the dose is 8kGy. Further study indicates that vitamin C, violaquercitrin and total sugar inhibit the irradiation degradation of chlorpyrifos in Asparagus. |
