Comparative Study of Flame Atomic Fluorescence Spectrometry and Inductively Coupled Plasma Mass Spectrometry for Determination of Cadmium in Lead-Zinc Ores
The flame atomic fluorescence spectrometry(FAFS)and inductively coupled plasma mass spectrometry(ICP-MS)were used to determine cadmium in lead-zinc ores.Through comparative study,the correlation coefficients of calibration curves of the two methods were good(r>0.999 5),and the limit of detection,accuracy,and precision of the methods met the requirements of the quality specifications.After comparing the actual samples of lead-zinc ores,there were no significant difference between the two methods.Compared to ICP-MS,the FAFS has shorter measurement time and higher precision,making it suitable for the determination of large quantities of lead-zinc ore samples.
