| 摘 要： | 对电子化工原料及产品草酸钴、氯化钴、钴酸锂中的铁进行测定,基体中高含量的钴对铁(约0.001%)的测定造成了干扰.用乙酸乙酯萃取其中的铁,采用邻菲罗林光度法测定,测定结果相对标准偏差1.46%～2.69%,加标回收率98.49%～98.82%.方法简便、快速,目前已应用于实际工作中.

| Abstract: | The high content cobalt in some electronic materials and products like COC4O4, CoCl2 and LiCoO2 would interfere the determination of low content iron. A speetrophotometer method which was fast, simple and convenient, was established after extracted the iron in the sample with ethyl acetate. The range of RSD was 1.46 % - 2.69 % , the recovery was 98.49 % - 98.82 %. The method had been applied in practical operation. |
