摘要
为了对中草药中残留农药的去除提供新的方法和依据,本文研究了辐照剂量、含水量等不同因子对人参中氨基甲酸酯及有机磷农药去除率的影响,同时探讨了白茯苓等不同中草药基质中两类农药同一剂量辐照的去除效果。结果表明:电子束辐照可有效加速氨基甲酸酯和有机磷农药残留的降解;低剂量辐照下的农药降解不如高剂量的效果明显,农药辐照降解率随着辐照剂量的增大呈增加的趋势,并在4~10 kGy区间内有波动;在不同的中草药基质中,有机磷农药降解效果普遍优于氨基甲酸酯农药。
In order to put forward new method and basis to remove pesticide residues in Chinese herbs, the influence factors such as irradiation doses and water content of electron beam irradiation on degradation efficiency of earbamate and organophosphorous pesticides in ginseng are investigated. Additionally, the irradiation degradation of two pesticides treated with the same dose in several traditional Chinese herbal medicines like Baifuling is also studied. The irradiation can effectively degrade these pesticide residues in herbal medicines; the efficiency of lower doses are inferior to higher doses. The degradation rate rises when dose increases, and varies among 4 - 10kGy in different Chinese herbal medicines. The degradation efficiency of organophosphorous pesticides is better than those of carbamate pesticides.
