    臭氧水对黄瓜和青菜中6种有机磷农药残留的去除效果

    Removal effect of six organophosphorus pesticide residues in Brassica chinensis and cucumbers by ozone water

    • 摘要: 考察了臭氧水浸泡处理对黄瓜和青菜上6种有机磷类农药残留的去除效果。发现臭氧水浸泡的去除效果优于自来水处理,在通臭氧30 min后,其对青菜和黄瓜中乙酰甲胺磷、二嗪磷、马拉硫磷、毒死蜱、喹硫磷和三唑磷的总去除率分别为26.4%~65.2%和22.7%~75.4%,净去除率分别为6.8%~17.3%和4.4%~45.4%。对6种农药在臭氧水中降解速率的研究表明,臭氧处理对残留农药的去除效果与果蔬种类、处理时间及残留物种类有关。

       

      Abstract: Removal effect of six organophosphorus pesticide residues in cucumbers and Brassica chinensis L.by ozone water was investigated.The results showed that the removal effect by ozone water was better than that by tap-water.With ozone for 30 min,total removal rates of acephate,diazinon,malathion,chlorpyrifos,quintiofos and triazophos on B.chinensis and cucumbers were 26.4%-65.2% and 22.7%-75.4%,respectively.And net removal rates of them were 6.8%-17.3% and 4.4%-45.4%,respectively.The study on the degradation rate of six pesticides in ozone water was indicated that the removal efficiency of pesticide residues by ozone was relevant to the species of fruits or vegetables,the treating time of ozone and the types of residue.
