描述了89Sr样品中含量为10-6级的90Sr测定方法。采用纸层析法先使钇与大部分锶分离,再通过对原点纸段半衰期的测定确定90Y和90Sr的准确含量,从而确定出80Sr样品中90Sr的含量。该方法简便;易行,有效地达到了实际使用的目的。
A procedure used to determine 90Sr content in 89Sr product was developed.According to the decay principle
90Sr maintains long term equilibrium with daughtercoy. So
90Sr content can be determined through 90Y determination. Paperchromatography was used to separate yttrium from stronium
accurate determinationsof 89Sr content and 90Y content were obtained on the basis of half-life measuringmethod. At last
90Sr content was determined. The procedure is effective
simple andconvenient.
