本文报导了用无水乙醇与乙醚的混合液对硝酸锶中的硝酸钙进行萃取之后,以碳酸钠为滴定剂测定样品中锶、钡合量,然后减去钡量(另取样品用比浊法测得),从而计算出样品中锶含量的分析方法.该法简便、快速、准确.
This paper reports the extraction of calcium nitrate from strontium nitrate using a mixture of absolute ethanol and ether. The concentration of strontium and barium in the sample was determined using sodium carbonate as the titrant, and then the amount of barium was subtracted Method) to calculate the strontium content in the sample analysis method.The method is simple, fast and accurate.
