| Abstract: | Add the reduced iron powder into Panfei tube contained the sample,heat to make mercury separated from coexisting elements;The optimal conditions for the determination of mercury by hydride generation atomic fluorescence spectrometry were studied The detection limit of mercury is 0 05ng/mL the linear range is 0 5-250ng/mL for Hg*",the recoveries of mercury are 94%-101% The method has been applied to determine mercury in zinc refined ores with satisfactory results |
