本文综述了海水中微量金属离子的分离、富集方法的研究概况,其中包括了微量营养金属离子铜、铁、锰;痕量金属离子铀、金、钍等;某些放射性金属离子锶,铍、铈、镭等以及一般微量金属离子锗、镓、锌、铝、钴、(?)等等计30余种。文中按共沉淀法,溶剂萃取法,离子交换色层法三大类进行介绍。除对上述各法的特点及应用情况加以讨论外,还对某些方法今后的发展方向提出了初步见解。本文(?)集有关文献计170余篇。
This review summarizes the research progress of the methods for the separation and enrichment of trace metal ions in seawater, including micronutrient metal ion copper, iron and manganese; trace metal ions such as uranium, gold and thorium; some of the radioactive metal ions strontium, beryllium , Cerium, radium and so on, as well as general trace metal ions germanium, gallium, zinc, aluminum, cobalt, (? In this paper, coprecipitation, solvent extraction, ion exchange chromatography three categories are introduced. In addition to discussing the characteristics and application of the above-mentioned laws, some preliminary opinions on the future development of certain methods are also proposed. This article (?) Sets the literature more than 170 articles.
