报道了一种用超临界流体萃取水果蔬菜中多种残留有机磷的方法。样品与硅藻土混合后用超临界ＣＯ２ 提取（萃取压力为３０ＭＰａ，温度为５０℃），乙酸乙酯收集。２ ｇ 样品农药残留回收率为８２％ ～１０８％ ，相对标准偏差为４．６％ ～１１％ （ｎ＝ ６）。测定了西红柿、草莓、金桔和柠檬等样品。测得的结果与传统方法一致，本方法快速、准确。
A supercritical fluid extraction method for extracting residual organophosphorus from fruits and vegetables was reported. Samples were mixed with diatomaceous earth and extracted with supercritical CO 2 (extraction pressure 30 MPa, temperature 50 ° C). Ethyl acetate was collected. The pesticide recovery of 2 g samples ranged from 82% to 108% with a relative standard deviation of 4.6% to 11% (n = 6). Determination of tomatoes, strawberries, kumquat and lemon and other samples. The measured results are consistent with the traditional method, the method is fast and accurate.
