中文摘要：
农药残留分析的样品来源多样、基体复杂,而传统的离线样品前处理中,萃取、转移、净化、浓缩等步骤分步进行,繁琐费时、样品损失较大、精密度和重现性差,因此,发展样品前处理-色谱在线分析技术可望解决这些问题。本文综述了近年来固相萃取、固相微萃取、基质固相分散萃取、膜萃取、微波辅助萃取、加速溶剂萃取和超临界萃取等样品前处理-色谱在线分析农药残留的研究进展,并展望了其应用前景和发展方向。引用文献54篇。
英文摘要：
Traditional off-line residues sample are time-con preparation techniques for the diversity and complex matrix pesticide suming, and have poor sensitivities and reproducibility. Online sample analytical time but also usually provides better sensitivity and accuracy his paper, the recent progress sample preparation online coupled with For the determination of pesticide residues is reviewed. These sample solid-phase extraction, solid-phase microextraction, matrix solid-phase ction, microwave-assisted extraction, accelerated-solvent extraction, etc. At last, the future development of the somple prpation method is preparation not only shortens than off-line techniques. In t chromatographic techniques f preparation methods include dispersion, membrane extra supercritical fluid extraction, prospected.
