Determination of Micro Amounts of Mercury in Lead Concentrates by Atomic Fluorescence Spectrometry

Ting Liu

Abstract

Samples were dissolved in equa regia(10%).In a medium of HCl,the optimized determination conditions of mercury by atomic fluorescence spectrometry were discussed.The detection limit of this method for mercury is 0.05?ng/mL,with linear range of 0.5～25?ng/mL.The recovery of standard addition for mercury is 99.3%～106%.
