【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 trace mercury with a good precision.更多还原
