摘要
超临界 CO2 流体与金属配合技术相结合开辟了重金属萃取的新途径。本文介绍了超临界 CO2流体萃取重金属的研究现状 ,总结了影响萃取的因素 。
The Combination of supercritical carbon dioxide fluid extraction and complexing action is a new way to extract heavy metals from different media, especially environmental samples. Recent studies have demonstrated the feasibility of recovering heavy metals by in situ chelation using a SC-CO2 mobile phase: Development about extraction of heavy metals by SC-CO2 fluid is reviewed, and factors affecting the extraction are discussed. Finally, a more broad application range is prospected with an in-depth research of supercritical carbon dioxide fluid extraction of heavy metals.
