有机氯农药的固相萃取实验条件研究

摘要

Solid phase extraction technology is one of the most frequently used sample preparation methods.This method is widely used in the pretreatment of water.It is also applied to trace organic compounds in the air and biological sample is determined by the components of enrichment process.This experiment uses automatic solid phase extraction apparatus to extract the chlorine pesticide water compounds.The enrichment of solid phase extraction was evaluated by recovery of standard addition.This paper discussed the influence of different experimental conditions on the extraction efficiency.%固相萃取技术是一种最常使用的样品制备方法,被广泛用于水样的预处理、空气中痕量有机化合物和生物样品中被测定组分的富集过程。实验使用全自动固相萃取仪萃取水中的有机氯农药类化合物,以空白加标回收率来评价固相萃取的富集效率,讨论了固相萃取实验条件的不同对样品萃取效率的影响。
