摘要
介绍了一种快速检测蔬菜有机磷农药残留的方法。以黄瓜为试材，通过准 确度、精密度和灵敏度的分析，以及与国家标准方法——气相色谱法的比较，对该方法进行 了实验学评价。结果表明，该方法对敌敌畏、甲基对硫磷、辛硫磷、氧化乐果和甲胺磷的回 收率分别为98.75%、83.00%、91.00%、70.50%和86.00%； 最低检测限量分别为0.05、0.02、0.3、0.5、0.5mg ·kg^(-1)。多次平行测定变异系数小于4%，可以满足半定量分析的要求。
A rapid Testing method of organophosphorus pesticides residue in vegetables was introduced in this paper. The experimental evaluation was done by means of degree of accuracy，precision and sensitivity，and by compa ring with gas chromato-graphy method which is standard method of our countr y.The results showed that the rate of recovery for this method was over 70% ，the comparatively standard variance was less than 4%，and the lowest d etection limit was 0.02～0.5mg·kg^(-1). All of these show that this kind of rapid testing method can satisfy the need of user for rough detection of organophosphorus pesticides residue in vegetables.
