Abstract: The main determination methods of mercury in soil are atomic fluorescence spectrometry, cold atomic absorption spectrometry and inductively coupled plasma mass spectrometry(ICP-MS). The characteristics of these three methods are studied in this paper. The results show that each method can meet the requirements of the determination of mercury in soil.
Keywords: soil; mercury; atomic fluorescence spectrometry; cold atomic absorption spectrometry; inductively coupled plasma mass spectrometry(ICP-MS)
