摘要
综述了近年来衍生 超临界流体萃取环境样品和环境模拟样品中金属离子的研究报道 ,结合作者的研究工作 ,着重评述了超临界流体萃取不同环境样品、环境模拟样品中金属离子的原理、萃取过程的动力学模型、衍生剂的选择原则、金属螯合物在超临界流体中的溶解度理论、影响萃取效率的因素、金属离子超临界流体萃取应用研究现状与进展等。利用流体与基体改性技术实现了金属离子和金属螯合物的超临界流体萃取 。
The supercritical fluid extraction theory on the metal ions from different kinds of samples, solubility theory of chelating agents in supercritical fluid, kinetics model, rules of choosing chelating agent, the advances of applying research, the effecting factors of the extraction efficiency and the application and technology of supercritical fluid chelating extraction of metal ions are mainly discussed and evaluated in this paper. The results of the review indicate that the technology of supercritical fluid chelating extraction metal ions can be used in environmental samples successfully.
