| Abstract: | A convenient method was established to determine arsenic and mercury contents in iron ores.The iron ores were dissolved in HNO3-HCl solution by water-bath digestion at low temperature,and the determinations of arsenic and mercury contents were performed by hydride generation-atomic fluorescence spectrometry with a sequential injection system.The choice of digestion reagents is discussed in this paper.Some important interference factors were studied to obtain the optimum measurement conditions,e.g the concen... |
