| 摘 要： | 试样经硝酸一氯酸钾饱和溶液分解，以氨水沉淀过滤分离杂质，滤液在乙酸-乙酸铵缓冲介质中，用乙酸铅沉淀溶液中的钼酸根生成钼酸铅，沉淀通过灼烧，直至恒重。氨水分离后残渣中的钼经硝酸、氢氟酸、高氯酸分解后，使用ICP等离子发射光谱测定，予以补正。

| Abstract: | The samples were decomposed by HNO3-KCLO3 saturated solution, most of the interfering elements were separated by NH3· H2O through precipitation. In acetic acid-ammonium acetate buffer medium, use lead acetate to precipitate molybdate in filter liquor to genevate precipitation, then bum it until constant weight. After the separation, Mo in ammonia residue was decomposed by nitric acid, hydrofluoric acid and perchloric acid, the use ICP plasma e- mission spectrometry to determine it for correction. |
