摘要
采用HF -H2 SO4除硅 ,萃取 -原子吸收法测定炼银炉渣中的金。样品加标回收率为92 .0 %~ 1 0 4 .0 % ,相对标准偏差为 3.8% (n =1 1 )。将该法应用到炼银炉渣中金的测定 ,结果符合分析质量要求。
A method for the determination of gold in silver smelting slag by AAS after decomposition of the sample and removal of silicon with HF H 2SO 4 was reported in this paper.And gold was preconcentrated by solvent extraction. The recovery of standard addition for gold is 92.0%~104.0% with precision of 3.8% RSD ( n =11). The method has been applied to the determination of gold in silver smelting slag samples with satisfactory results.
