地球化学样品中有机农药残留分析预处理方法新进展

New advances in the pretreatment of geochemical samples during the analysis of organic pesticide residues

摘要: 在对地质样品进行有机农药残留分析的过程中，样品预处理是重要的步骤之一。概述了近年采样品预处理方法的新进展，简要介绍并对比了固相萃取（SPE）、固相微萃取技术（SPME）、微波提取技术（MAE）、超临界萃取（SFE）、加速溶荆提取（ASE）等方法。

Abstract: Pretreatment is one of the important procedures during the analysis of organic pesticide residues in geochemical samples. This paper discusses the recent advances in sample pretreatment methods and briefly introduces and compares the technique of SPE, SPME, MAE, SFE and ASE.
