底质中有机磷农药残留分析方法

有机磷农药是继有机氯农药以后被广泛应用的一类农药，它对生物体具有一定毒性，因此对有机磷农药的充分提取及检测就密切关系到人们的饮食安全。传统提取底质中有机磷的方法为索式提取或者采用有机溶剂对底质直接萃取，而文章采用亲水溶剂对底质进行萃取，并通过固相萃取技术对其进一步纯化，气相色谱一质谱法检测，对多种有机磷农药的分离度较好。

The Analysis of Organophosphorous Pesticide in the Soil Environmental Monitoring Center of Heilongjiang Province

The organophosphorous pesticides,which have been widely used after the using of ganochlorine,are toxic in a way to the organism.So the extraction and monitoring of organophosphorous pesticide are related to the security of human-body.This method takes the hydrophilic solvent to extract the components in the soil culture and the technique of solid-extraction to purify,instead of the traditional methods such as Soxhlet extractor.We adopt GC-MS to detect the organophosphorous pesticide and get excellent effici...
