贵金属有许多独特的性能,在现代科学和尖端技术中应用日益广泛。但稀缺、昂贵,因而其分离、富集越来越为人们所重视。磷酸锡作为无机离子交换剂,除耐高温和强放射性外,还具有较高的化学稳定性和良好的选择性。作者等已应用于液相色谱方面的研究工作,并取得了一定的成效。但所用的磷酸锡沉 Precious metals have many unique properties that are increasingly used in modern science and cutting-edge technologies. But scarce and expensive, so its separation and enrichment are getting more and more attention. Tin phosphate as an inorganic ion exchanger, in addition to high temperature and strong radioactivity, but also has high chemical stability and good selectivity. The author has been applied to the research of liquid chromatography, and achieved some results. However, the use of tin phosphate Shen
