摘　　要：高效氯氟氰菊酯是一种广泛使用的杀虫剂,采用碱性电解水处理含有高效氯氟氰菊酯农药的苹果,研究碱性电解水对果蔬中的农药残留的去除效果,并探究其作用的最优时间、方式、p H和温度。发现其降解效率与反应时间、p H、温度有直接关系,处理方式对降解效果影响不大。随着反应时间的延长、p H的升高或温度的升高,降解程度也增加。结果表明,碱性电解水对于高效氯氟氰菊酯农药有较好的去除效果,最佳条件是p H11.0的碱性电解水,在20℃静置处理苹果1.5 h,降解率可以达到75%以上。Lambda-cyhalothrin is a widely used pesticide. In order to reduce the residues, alkaline electrolyzed water is used to treat with fruits and vegetables contained with lambda-cyhalothrin. It was studied the degradation efficiency and the proper time, p H and the temperature. It found that the degradation efficiency with the reaction time, p H, temperature has a direct relationship, and has no direct relationship with the treatment. With the increase of reaction time, p H and temperature increases, the degree of degradation also increased. The results showed that the alkaline electrolyzed water can effectively decline the residues of lambda-cyhalothrin. Alkaline electrolyzed water of p H11.0 is the best condition, at 20 ℃ stand processing apples 1.5 h.
