方法基于锶与钡铬酸盐溶解度的差异进行分离。在有很大过量氯化铵存在下的醋酸溶液中,当BaO:SrO=1:1时分离效果很好,此法可用于BaO>10mg的含锶试样及矿石中BaO的测定。
The method is based on the differences in the solubility of strontium and barium chromate. In the presence of a large excess of ammonium chloride in acetic acid solution, when BaO: SrO = 1: 1 separation effect is very good, this method can be used BaO> 10mg of strontium containing samples and ores BaO determination.
