研究了用氢氧化铁共沉淀分离富集高纯阴极铜中铅、铋和碲的最佳条件与 ICP- AES法的最佳工作条件。在选定的最佳条件下测铅、铋和碲的检出限分别为 0 .0 0 34 ,0 .0 1 3和 0 .0 0 77μg·ml- 1 ,回收率分别为 97.8%~ 1 0 0 .8%、95.5%~ 1 0 6.5%和 98.5%~ 1 0 0 .5%。测定高纯阴极铜中铅、铋和碲 ,结果满意。
The optimum conditions for the separation and enrichment of lead, bismuth and tellurium in high purity cathode copper by ICP-AES with iron hydroxide coprecipitation were studied. The detection limits of lead, bismuth and tellurium were0.034, 0.013 and0.077μg · ml-1 respectively under the optimal conditions, the recoveries were 97.8% -1 0 0 .8%, 95.5% -1 0 6.5% and 98.5% -1 0 0 .5%. Determination of high purity cathode copper lead, bismuth and tellurium, with satisfactory results.
