| titleOfInvention | Determination method of trace iron in aluminum-containing phosphoric acid solution and aluminum masking agent therefor |
| abstract | The invention relates to the technical field of a determination method of trace iron in an aluminum-containing phosphoric acid solution, and particularly to a determination method of trace iron in an aluminum-containing phosphoric acid solution and an aluminum masking agent for the determination method. The determination method comprises two steps of drawing a standard work curve of iron content and testing the iron content in a test sample solution. The determination method of the invention is simple in operation, high in test accuracy, and good in reproducibility, not only overcomes the defect in the prior art of impossible to detect due to the present of white aluminum hydroxide precipitate, but also solves the problems of poor trace iron detection accuracy and high cost in the track iron determination process by the atomic absorption spectrophotometry, and effectively expands the application scopes of determinating iron content in the phosphoric acid with the phenanthroline spectrophotometric method. |
