鈮鐵中磷的快速測(cè)定方法探討
Discussion on Rapid Test Method for Phosphorus Content in Ferroniobium
-
摘要: 以酒石酸掩蔽鈮鐵中鈮的干擾,采用抗壞血酸-磷钅必鉬藍(lán)光度法測(cè)定磷。試驗(yàn)結(jié)果表明,該測(cè)定方法具有簡(jiǎn)便、快速、準(zhǔn)確性及再現(xiàn)性均好的優(yōu)點(diǎn)。Abstract: 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.
