高纯度的铷、铯化合物,在国防工业上,对其杂质的含量均有一定的要求。锂的含量低,取一定量的主体组成铷和铯的化合物(包括铬酸铷、铬酸铯),容易电离,致使结果导致正误差。××化学试剂厂生产的99%的铷铯盐中的锂,没有分析结果。KYCTAC等人均以标准加入法为测定的主要方法。检测范围只能达到1×10~(-2)%手续繁琐,准确度差。应用萃取分离测定氯化铷、铯中的锂
High purity rubidium, cesium compounds, in the defense industry, the content of its impurities have certain requirements. Low lithium content, take a certain amount of the main composition of rubidium and cesium compounds (including rubidium chromate, cesium chromate), easy to ionize, resulting in a positive error. 99% of the lithium rubidium cesium salt produced by ×× Chemical Reagent Factory has no analytical result. KYCTAC and others are standard methods for the determination of the main method. Detection range can only reach 1 × 10 ~ (-2)% tedious procedures, the accuracy is poor. Application of extraction and determination of rubidium chloride, cesium lithium
