| 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. |
