近年来,离子交换作为分析化学中的一种分离技术,其发展主要是研制螯合型离子交换树脂和在有机溶剂中进行分离,两者的目的均是为了提高分离金属离子的选择性。我们通过调研和两年多来的工作,认为活性氧化铝对某些阴离子,特别是对硫酸根离子有很高的选择性,并且在某些方面其实用价值高于阴离子交换树脂,所以,有必要讨论活性氧化铝在阴离子分离方面的应用。
In recent years, ion exchange as a separation technology in analytical chemistry, its development is mainly the development of chelating ion exchange resin and separation in organic solvents, both for the purpose of increasing the selectivity of the separation of metal ions. Through our research and over two years of work, we believe that activated alumina is considered to have high selectivity to certain anions, especially to sulfate ions, and in some respects its practical value is higher than that of anion exchange resins. Therefore, It is necessary to discuss the application of activated alumina in anion separation.
