摘　　要：A series of glucose derivatives have been used as chelating reagents to extract metal ions in supercritical carbon dioxide. With perfluoro-l-octanesulfonic acid tetraethylammonium salt as additive, glucose derivatives were selective for Sr^2＋ and Pb^2＋ extraction in supercritical carbon dioxide.A series of glucose derivatives have been used as chelating reagents to extract metal ions in supercritical carbon dioxide.
