钡、锶属同族元素、性质相似,故分离困难。我们用离子交换法通过原子吸收法检测,找到钡、锶在交换过程中的规律,并用分步离子交换制得了高纯低锶碳酸钡。
Barium, strontium belong to the same family of elements, similar in nature, so the separation is difficult. We detected by ion exchange method by atomic absorption method to find barium and strontium in the exchange process, and with a step-by-step ion exchange made of high purity and low strontium barium carbonate.
