随着电子、自动化、宇航和原子能工业的飞跃发展,铷、铯资源的勘探和开发愈加引起重视。遗憾的是在自然界仅找到铯的矿物,因而从液体矿-卤水中提取它们,就成为一条重要途径。从基体为碱与碱土金属的卤水中分离出铷、铯存在着较大的困难,且又缺乏特效试剂,因而目前主要用仪器分析法测定,其中以火焰分光度法最为普及。我们用四苯硼钠将卤水中铷、铯随钾共沉淀分离,继溶于正丁酮-甲醇-水
With the rapid development of electronics, automation, aerospace and atomic energy industries, the exploration and development of rubidium and cesium resources have drawn more and more attention. Unfortunately, only cesium minerals are found in nature, so extracting them from liquid mines - brine is an important avenue. It is difficult to separate rubidium and cesium from the alkali and alkaline earth metal brine, and there is a lack of specific reagents. Therefore, it is mainly determined by instrumental analysis, of which flame-spectrometry is the most popular method. We use sodium tetraphenylborate brine in the rubidium, cesium with potassium coprecipitation separation, followed by dissolved in methyl ethyl ketone - methanol - water
