| Abstract: | The authors set up the procedures to determine the trace total mercury in gas by cold vapor atomic absorption spectrometry and atomic fluorescence spectrometry. Sampling mercury from natural gas with I-active carbon, and the microwave oven digestion system is used for dissolution of the samples. The recovery and the relative standard deviation were 91% to 98% and less than 5% respectively. The method is simple, rapid, sensitive and accurate, the results were shown to be satisfactory. |
