摘要
研究了黑铜中银的分析测定方法。黑铜试样以高氯酸分解 ,在高氯酸 -硫脲介质中 ,用火焰原子吸收光谱法测定银。该方法测定的标准加入回收率为 98.4 %～ 10 4 .3%。
This paper studied Ag assay method in ferrous copper.After the ferrous copper samples was dissolved by perchloric acid,the gold within it was determined by flame atomic absorption spectrum method in perchloric acid and sulfourea.
