Until recently,little information was available in the literature regarding supercritical fluid extraction (SFE) of metal species.Direct extraction of metal ions is highly inefficient because of charge neutralization requirements and the week solute–solvent interactions.However,when metal ions are chelated with organic ligands,supercritical CO2 can dissolve the chelating metal complex
直到最近,几乎没有资料可在文学方面的超临界流体萃取（萃取）金属物种.直接萃取金属离子的效率非常低,因为电荷中和的要求和溶质溶剂的相互作用–周.然而,当金属离子螯合的有机配体,超临界二氧化碳溶解螯合金属配合物
