铌铁中磷的快速测定方法探讨

Discussion on Rapid Test Method for Phosphorus Content in Ferroniobium

以酒石酸掩蔽铌铁中铌的干扰，采用抗坏血酸－磷钅必钼蓝光度法测定磷。试验结果表明，该测定方法具有简便、快速、准确性及再现性均好的优点。

With tartaric acid masking interference by niobium in the ferroniobium,the ascorbic acid－ P－ Bi－ Mo blue photometry was used to determine the phosphorus content.The experiment result shows that the test method can provide such advantages as simple operation,rapid and accurate determination as well as good reproducibility.
