果蔬中有机磷农药残留快速检测方法研究

提出了一种酶活性抑制快速检测果蔬中有机磷农药残留的新方法,并制成了相应的快速检测卡。研究了该方法的准确度、精密度和灵敏度。对敌敌畏、氧化乐果、甲基对硫磷、辛硫磷和甲胺磷的检测限分别为0.08、0.46、0.12、0.28、0.44mg/kg,回收率为98.9%、82.5%、90.0%、72.6%、88.4%,检测时间为30min,可以满足半定量分析的要求,对我国小规模、分散式的果蔬生产经销体系具有较强的适用价值。

Research on the Method of Rapid Testing for Organic Phosphorus Pesticides Residue in Vegetable

A new technique of rapid testing of organic phosphorus pesticide residue in vegetables with enzyme activity represses was presented. The rapid examination card to organic phosphorus pesticide residue was made. Veracity, the sensitive and precision were tested,The lowest detection limit was 0.08-0.44 mg/kg and average reclaiming velocity was 98.9 %-88.4 % and proof-test time was 30 min.
