固相萃取作为一种新型的预处理方法,近年来得到了广泛的应用和发展。因其具有有机溶剂使用量少、操作简单、选择性高、重现性好等特点,非常适合水中痕量有机物的富集和浓缩。本文阐述了固相萃取的基本原理、分类及其常用吸附剂和洗脱液的种类,并以水中多环芳烃、有机磷农药的预处理为例,介绍了固相萃取技术在水样分析中的应用。

고상췌취작위일충신형적예처리방법,근년래득도료엄범적응용화발전。인기구유유궤용제사용량소、조작간단、선택성고、중현성호등특점,비상괄합수중흔량유궤물적부집화농축。본문천술료고상췌취적기본원리、분류급기상용흡부제화세탈액적충류,병이수중다배방경、유궤린농약적예처리위례,개소료고상췌취기술재수양분석중적응용。
As a new pretreatment method, the solid phase extraction ( SPE) was obtained extensive application and development. The SPE had advantages of lower dosages of organic solvent, simple operation, high selectivity, and good reproducibility, etc. This technique highly fit to enrich and concentrate the trace organic compounds in water. The principle and classification of the SPE, and its type of absorbent and eluent were summarized. The application of SPE in the analysis of water was also introduced based on the examples of the pretreatment of polycyclic aromatic hydrocarbons and organophosphorus pesticides.
