摘　　要：介绍了离子液体在萃取分离环境污染物和环境监测等方面的应用;萃取分离环境污染物中着重介绍了离子液体在液/液萃取、固体微萃取、液相微萃取和半透膜法富集等方法中的的应用;介绍了环境监测中运用的传感器分析和色谱分析等方法。分离环境污染物主要优势是萃取率高、选择性高等。环境监测方法具有重现性好、不存在二次污染等特点。The application of ionic liquids in extraction of the environmental pollutants and environmental monitoring was intro- duced,including liquid/liquid extraction, solid phase microextraction, liquid phase microextraction, semipermeable membrane preconeentration,sensor analysis and chromatography analysis. The main advantages of ionic liquids in extraction of environmental pollutants were high extration efficiency and high selectivity. The environmetal monitoring methods using ionic liquid technology had good reproducibility and no second pollution.
