| Abstract: | Soils taken from different places and depth were digested with wetting digestion method. At the optimal conditions, the contents of trace arsenic and mercury elements were determined by atomic fluorescence spectrometry. The results showed that., the relative standard deviation was 1.4%-2.3% and 2.0%-3.5%, the recovery was 91%-106% and 96-102% for As and Hg, respectively. The method was simple and rapid. The detection limit and accuracy of the method can meet the requirement for a soil test. |
