锂是原子能工业不可缺少的原料,铷和铯主要用于制造光电池和发光物质,所以它们的分析也引起了重视。但这三种元素的电子层结构决定了它们的性质活泼、盐类的溶解度大,较难形成有色的、稳定的络合物,这就给分析带来了困难。随着有机试剂的发 Lithium is an indispensable raw material for the atomic energy industry. Rubidium and cesium are mainly used in the manufacture of photovoltaic cells and luminescent substances, so their analysis has drawn great attention. However, these three elements of the electronic layer structure determines their nature of lively, salt solubility, the more difficult to form a colored, stable complex, which gives the analysis of the difficulties. With the development of organic reagents
