| 中文摘要: |
| 研究新癸酸钴中不同氧化态钴分离及测定的方法。根据二价钴和三价钴与乙酰丙酮形成的配合物溶解性的不同，实现不同氧化态钴的有效分离；根据配合物稳定常数的不同，利用络合滴定法，测定新癸酸钴中二价钴含量。用本方法对自制及市售新癸酸钴样品的进行分离及测定取得满意的效果。 |
| 英文摘要: |
| The separation and determination of the cobalt in different oxidation states in cobalt neodecanoate were investigated. The effective separation of divalent cobalt， Co (II)， and trivalent cobalt， Co (III)， was carried out by using acetylacetonate since the formed complexes had different solubility. The determination of Co (II) content in cobalt neodecanoate was carried out by using complexometric titration and based on the difference in stability constant of the complexes. Through this method， separation and determination of the cobalt in self-made and commercial neodecanoate cobalt samples were successfully achieved. |
