近年来,对溶液络合物的研究日益增多,了解金属在水溶液中的离子状态,也是当前我们无机化学工作者的重要任务之一。研究这些问题的方法很多:诸如离子交换法、光度法、电位滴定法、极谱法、溶解度法及萃取法等等。本文仅将对萃取法研究水溶液的诸问题作较详细的介绍。萃取法又称分配法,是以上所述方法中此较简单、快速而又准确的方法之一,应用溶剂萃取不需要复杂的仪器,所需用的研究物质很少,因此近年来很
In recent years, the research of solution complexes has been increasing day by day. It is one of the important tasks of our inorganic chemistry workers to understand the ionic state of metals in aqueous solution. There are many ways to study these problems: ion exchange, spectrophotometry, potentiometric titration, polarography, solubility and extraction. This article will only extract the aqueous solution of the problems described in more detail. Extraction method, also known as the distribution method, is one of the simpler, faster and more accurate methods described above. The application of solvent extraction requires no complicated equipment and requires little research material. Therefore, in recent years,
