摘要
研究并建立了在同一体系中经溶剂萃取用电感耦合等离子体发射光谱测定纯金中 10种杂质元素的方法。银、铜、铁、铅、锑、铋、钯、镍、铬、锰的检出限分别为 0 .0 0 4 8,0 .0 0 4 6 ,0 .0 0 2 2 ,0 .0 16 ,0 .0 15 ,0 .0 0 5 4,0 .0 0 5 8,0 .0 0 37,0 .0 0 5 3,0 .0 0 0 6 μg/ml,回收率均在 98.7%～ 10 2 .9%之间 ,相对标准偏差为 1.2 %～ 5 .8%。
The paper developed a method of determining 10 types of impurity elements contained in the gold using inductively coupled plasma emission spectrometric method after the gold has been extracted with solvent in the same system.The detection limit of silver, copper, ferrum, plumbum, stibium, bismuth, palladium, nickel, chromium and manganese are 0.004 8, 0.004 6, 0.002 2, 0.016, 0.015, 0.005 4, 0.005 8, 0.003 7, 0.005 3 and 0.000 6 μg/ml respectively, the recovery rate of them is in the range of 98.7%～102.9%, and the relatively standard deviation is from 1.2% to 5.8%.
