固相微萃取技术及其在环境监测中的应用

介绍了90年代初推出的一种新的样品前处理技术－固相微萃取技术。它与传统的萃取法相比具有分析周期短、简捷、灵敏度高，无须使用溶剂，适于现场监测等优点，目前已成功地用于各基质样品如：土壤、水、大气中环境污染物的分析。文章还对其基本原理、固相涂层、操作模式展开了讨论。经分析认为该技术有着广阔的推广和应用前景。

Solid Phase Micro-Extraction Technique andIts Applicationin Environmental Monitoring

Solid phase micro extraction technique, a recently developing technique for sample treatment in 1990s, was introduced. Compared with traditional extraction methods, it had such characters as short analysis period, simplicity, high sensitivity, without solvent and suitable for field monitoring. The method had be successfully used in all kinds of substrate samples, such as the pollutants in soil, water, atmosphere. Its basic principles, solid phase coasting and operation program were discussed in this paper. It can be believed that this technique can be widely used in many fields of chemical analysis.
