摘要
试验了用冷原子吸收法测定铜精矿、铅精矿和锌精矿中微量Hg的适宜条件,拟定出适于3种精矿中3~500μg/gHg的测定方法。方法的RSD(n=11)<10%,回收率为90%~102%,与双硫腙光度法测定结果吻合。
The optimum conditions for determination of mercury in copper, lead and zinc concentrates by cold vapour AAS are investigated in detail. The method has been applied to the determination of Hg with its concentration level of 3~500 μg/g in copper, lead and zinc concentrates. The recoveries of Hg is 90%~102% with precision of <10% RSD( n =11). The results are in good agreement with those obtained from dithizone spectrophotometry.
