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

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.
