摘　　要：枸杞中有机磷农药残留超标成了影响其品质的问题。通过臭氧处理和碱处理对比研究,观察两种方法对枸杞中敌敌畏、乐果、马拉硫磷、三唑磷这四种有机磷农药残留的降解效果。实验结果表明,臭氧和碱水对以上四种有机磷农药均有不同程度的降解作用,其中臭氧对枸杞中敌敌畏的降解率达到了97.83%,碱水对枸杞中敌敌畏的降解率达到了98.68%。Orqanophosphorus pesticide residues in Lycium barbarum L. affect products＇ quality. Degradation of four kinds of organophosphorus pesticides, such as dichlorvos, dimethoate, malathion and triazophos, in Lycium barbarum L. were investigated by using ozone and alkali liquor respectively, Experimental results showed that both ozone and alkali liquor could degrade these four organophosphorus pesticides, degradation rate of dichlorvos in Lycium barbarum L. reached to 97.83% by using ozone ,and the degradation rate reached to 98.68% by using alkali liquor.
