臭氧水對果蔬農(nóng)藥降解效果怎么樣?
       利用臭氧水來去除果蔬農(nóng)殘的方式應(yīng)用較廣,市面上在售的臭氧果蔬清洗機(jī)為在家庭中使用臭氧水清洗果蔬提供了簡便的方法,為了發(fā)明出效果更好的臭氧果蔬清洗裝置,在實(shí)驗(yàn)室中對臭氧水降解農(nóng)殘的效果也進(jìn)行了大量的研究,一般臭氧水處理果蔬表面農(nóng)殘的實(shí)驗(yàn)裝置如圖1所示,表1提供了一些文獻(xiàn)中對臭氧水在果蔬基質(zhì)上對某些農(nóng)藥的降解效果。

臭氧水降解果蔬上農(nóng)藥殘留的效果
臭氧水降解果蔬上農(nóng)藥殘留的效果
       臭氧水浸泡對多種農(nóng)藥殘留均有良好的去除效果。用濃度為 0.4 mg/kg 臭氧水洗滌 30 min 后,菠菜中毒死蜱、腈菌唑、戊唑醇、聯(lián)苯菊酯、高效氯氟氰菊酯、高效氯氰菊酯、順式氰戊菊酯、苯醚甲環(huán)唑、啶蟲脒和吡蟲啉的殘留量分別降低了 53%、72%、73%、62%、67%、65%、78%、68%、64% 和 63%,與自來水清洗相比,清除效果提升了三到四倍。并且處理時(shí)間越長效果越好,例如臭氧氧化15 min 可使蘋果上毒死蜱、氯氰菊酯、嘧菌酯、己唑醇、甲基對硫磷、百菌清六種農(nóng)藥殘留降低 26.91%~73.58%,臭氧氧化 30 min 可使農(nóng)藥殘留降低 39.39%~95.14%。
