【摘要】 通过在高氯酸冒浓烟时多次加盐酸或氯化钠使铬元素生成CrCl₃将其除去，消除铬对铜精矿中铜含量测定的影响，适用于短碘量法测定高铬铜精矿中铜含量，该方法测定结果稳定性和准确性好，测定范围为5%～50%。更多还原

【Abstract】 In this paper, the effect of chromium on the determination of copper in copper concentrate is eliminated by adding hydrochloric acid or sodium chloride to CrCl₃ in the smoke of perchloric acid, the method is suitable for the determination of copper content in high chromium copper concentrate by short iodometry. The determination result has good stability and accuracy, and the determination range is 5%～50%.更多还原
