含少量钙钡的碳酸锶制备方法

Preparation method of stronium carbonate with low calcium and barium contents

使用工业上新型的除钙剂 ,由工业级原锶液 ,可直接制得化学纯碳酸锶。介绍了除钙工艺条件和沉淀碳酸锶的工艺条件。如果将除钙剂回收利用 ,则本工艺不失为一种经济有效的方法。

The chemically pure stronium carbonate could be prepared directly from the industrial grade stronium solution by using a new type of calcium removing reagent. The conditions for calcium removal and stronium carbonate precipitation process were also investigated. This method could be made even mone economical and effective if the calcium removing reagent could be recovered.
