固相萃取技术在环境监测领域中的应用及研究进展

The Application and Research Progress of Solid Phase Extraction in Environmental Monitoring Area

固相萃取(Solid Phase Extraction,SPE)技术是一个发展较快的试样预处理技术,主要用于样品中痕量物质的分离和富集。固相萃取技术克服了传统分离富集方法的一些缺点,得到了越来越多的关注,被广泛应用于环境、化学、石油化工、食品、农业、半导体、临床和制药、地质、核科学等领域。固相萃取技术由于其自身的优点,已经被成功应用于环境样品的样品前处理过程中。介绍了固相萃取的基本原理,固相萃取的装置,固相萃取的操作步骤,着重介绍了固相萃取在环境分析当中的应用。

Solid phase extraction is a fast developing sample pre-treatment technology for separation and concentra- tion of trace components.The disadvantages of the traditional separation-concentration methods are overcome by SPE technology.More and more attention has been given to SPE.SPE has been applied widely in environment area,chemical and petrochemical field,food and agriculture,semiconductor, clinical and pharmaceutical field,geological area,nuclear, etc.SPE has been applied successfully in the field of separation and concentration of environmental sample because of its unique advantages.In this paper, the basic principle of SPE, the solid phase extraction setup and the operating steps of SPE were introduced. The application of SPE in environmental analysis was introduced in detail.
