摘要
研究了一种用逆王水溶样冷原子吸收光谱测定铜精矿中汞的方法。铜精矿用逆王水消化后用测汞仪测定其中的汞含量。测定结果的相对标准偏差小于5%,回收率在91%～106%之间。与GB/T 3884.11-2005测汞方法比,操作简单容易。
A method for determination of mercury in copper concentrates by cold vapour atomic absorption spectrometry has been investigated in this paper. Copper concentrates were digested by lefort and the content of mercury was determined by mercury-measuring apparatus. RSD was less than 5 %, and the recovery was in the range of 91-106 %. Compared with the method of GB/T 3884.11-2005, it is much simpler.
