中文摘要:
      作者近期发展了一种具有普适性的相转移萃取技术,用于将各种过渡金属离子快速地从水相转移入非极性有机相,这种普适性方法使用乙醇作为辅助溶剂,具体包括将作为相转移试剂的十二胺溶解在乙醇中,然后和金属离子的水溶液混合搅拌,之后加入甲苯、己烷等非极性有机溶剂萃取相转移试剂与金属离子形成的配合物。本文对这种方法进行了综述并对其后续的一些发展进行预期和评估。
英文摘要:
      A general protocol to transfer metal ions from an aqueous solution to a nonpolar organic medium was developed recently, which involves mixing the aqueous solution of metal ions with an ethanolic solution of dodecylamine (DDA), and extracting the coordinating compounds formed between the metal ions and DDA into nonpolar organic medium, for example, toluene and hexane. The recent advances of this strategy was reviewed and an expectation/evaluation for its future directions was made.
