| 摘 要： | 根据铜锍的组成结构特点,建立了一种测定铜锍中铜含量的方法,重点讨论了混合酸对铜锍进行溶解的前处理及样品滴定过程。在4.80%~32.00%铜的测定范围内,加标回收率为97.70%~101.26%,相对标准偏差为0.24%~0.53%。方法能够较好地解决铜锍中铜含量测定难的问题。 |

| Abstract: | An iodometric titration approach was established for determination of copper in copper matte based on the composition and structure characteristics of copper matte. The focus of this paper is to investigate the sample pretreatment of dissolving copper matte sample with mixed acid and the titration procedures. Using the developed approach, the concentration range of copper that can be determined was from 4.80% to 32.00% with the relative standard deviations of 0.24 % -0.53%. The copper recoveries were from 97.70% to 101.26%. This study solved the problems in the determination of copper content in copper matte. |
