冷原子吸收法测定锌精矿中的汞

Determination of Mercury in Zinc Concentrate with Cold-Vapor Atomic Absorption

摘要: 采用冷原子吸收法测定出口锌精矿中汞,完善了国家标准锌精矿化学分析方法没有汞的测定方法之不足,该法测定范围为0.05～0.30μg/mL,回收率为99.6%～106.5%,变异系数为1.81%～3.02%,能满足微量汞测定要求.

Abstract: A new approach is established to determine of mercury in zinc concentrate.It is developed as a GB method for mercury.The method is possible to use with a linear range between 0.05~0.3 μg/mL.The recovery rate and the variety coefficient is in the range of 99.6%~106.5%,1.81%~3.02%,respectively.The proposed method has been employed for the determination of tracemercury with a good precision.
