摘　　要：快速溶剂萃取(ASE)是固体物质中污染物监测的一种样品前处理技术,它根据溶质在不同溶剂中溶解度不同,在较高的温度和压力下选择合适的溶剂,高效、快速地萃取固体或半固体样品中的待测物。阐述了ASE的技术性能和特点,分析了该技术在水环境监测中的应用,探讨了水体有机污染物监测技术的发展前景。Accelerated solvent extraction is a kind of sampling pre - treatment technology for monitoring poilutants in solid materials. The technology is used to select proper dissolvent under a relatively high temperature or pressure for quickly extracting waiting materials in solid or semi - solid samplings based on the nature that solubility of solutes vary in different dissolvents. ASE can be used for an overall monitoring of organic pollutants in water environment, and has a big potential for development.
