为了准确地测定铍,必须使铍与许多杂质,首先是铝和铁,分离开来,但根据化学性质,它与铝十分接近,所以要分离就遇到一定的困难。现时所用铍与铝、铁分离的方法有单宁酸盐法,隣位羟基喹啉法,碳酸盐法以及根据铍与铝的琥珀酸盐的水解性质不同的方法。上述方法中,有许多需要很长时间,要用贵重试剂,和不能保证必要的准确性。因此,我们提出任务,要研究没有上述缺点的方法。根据初步试验,可确定,如果用层析法先使铍与铝、铁分离,这任务就可很简单快速地解决。铍与铝、铁分离的工作,是以它们能够按照下 In order to accurately determine beryllium, beryllium must be separated from many impurities, primarily aluminum and iron, but chemically close to aluminum, so some difficulties have to be met. Currently used beryllium and aluminum, iron separation methods include tannate method, ortho-hydroxyquinoline method, carbonate method and according to the beryllium and aluminum succinate hydrolysis of different properties. Many of these methods take a long time, using expensive reagents, and failing to guarantee the necessary accuracy. Therefore, we propose the task of studying a method that does not have the above disadvantages. According to the preliminary test, it can be confirmed that if the first separation of beryllium from aluminum and iron by chromatography, this task can be solved simply and quickly. Beryllium works with aluminum and iron, so they can follow the next
