摘要/Abstract

摘要： 以氧化石墨烯为吸附剂, 建立一种固相萃取方法, 从花旗参茶饮料中萃取氟氯氰菊酯、七氟菊酯、氯戊菊酯、氯菊酯和联苯菊酯5种拟除虫菊酯类农药残留, 并通过单因素实验和正交实验对萃取条件进行优化, 考察氧化石墨烯用量、洗脱剂种类、洗脱剂体积和萃取时间对萃取效果的影响. 结果表明, 在最佳萃取条件下, 拟除虫菊酯类农药的富集效果较好, 氟氯氰菊酯、七氟菊酯、氯戊菊酯、氯菊酯和联苯菊酯的回收率分别为10598%,6593%,105.17%,93.69%,89.46%.

Abstract: Using oxide graphene as sorbent, we established a solidphase extraction method for the extraction of five pyrethroid pesticide residues of cyfluthrin, tefluthrin, fenvalerate, permethrin and bifenthrin from ginseng beverage. The extraction conditions were optimized by single factor experiment and orthogonal experiment. We investigated the effect of the amount of oxide graphene, the type and volume of eluent and the extraction time on the extraction. The results show that the enrichment effect of pyrethriod pesticide residues is better, the recovery rates of cyfluthrin, tefluthrin, fenvalerate, permethrin and bifenthrin are 105.98%,65.93,105.17%,93.69% and 89.46% respectively under the optimal extraction conditions.
