溶剂萃取作为一种分离技术已有悠久历史,由于它具有平衡速度快,处理容量大,分离效果好,回收率高以及操作简捷又宜遥控及自动化等特点,近二十年来它在解决核工业材料问题上起了很重要的作用。随着原子能科学技术的发展,溶剂萃取的研究与应用日益广泛,迄今已对周期表中的94个元素的萃取性能进行过研究。现在萃取法在无机化合物的分离和制备方面应用极广,它不仅是分析与制备难分离及高纯物质的重要手段,同时也是湿法冶金中经常采用的新技术。近年来萃取法在有色金属分离纯化方面的工业规模应用,更显示出这种技术的卓越经济效果。此外,萃取法在无机盐的提取和制备、有机化合物的分离,特别是在
As a separation technology, solvent extraction has a long history. Due to its characteristics of fast equilibrium, large processing capacity, good separation effect, high recovery rate, simple and convenient operation, remote control and automation, solvent extraction has been widely used in the nuclear industry Material issues play a very important role. With the development of atomic energy science and technology, the research and application of solvent extraction is more and more extensive. So far, the extraction performance of 94 elements in the periodic table has been studied. Nowadays, the extraction method is widely used in the separation and preparation of inorganic compounds. It is not only an important method for analyzing and preparing difficult-to-separate and high-purity materials, but also a new technique often used in hydrometallurgy. In recent years, extraction method in non-ferrous metals separation and purification of industrial-scale applications, but also shows the remarkable economic effect of this technology. In addition, the extraction method in inorganic salt extraction and preparation, the separation of organic compounds, especially in
