摘要
在硝酸钠存在下碘化钾-孔雀绿-水液-固体系浮选分离铋,采用石墨炉原子吸收法对高纯镍中痕量铋进行了分析。讨论并确定了实验的最佳测定条件,结果表明,Ri的检出限为1.9 ng/mL,回收率为101.7％-102.5％,相对标准偏差(n=6)为1.1％～1.4％。方法已应用于高纯镍中痕量铋的测定。
A new method for the flotation separation of Bismuth is used by the way of potassium iodide - malachite green - water liquid - soild system and determining Bismuth in high purity nickel in this essay. The limit of the method is 1. 9 ng/mL. The recycling rate ranks from 101.7 to 102. 5% . RSD is 1.1% - 1.4% . This method is applied to the determination of trace Bismuth in high purity nickel.
