| Abstract: | A method of determining trace mercury in water by the cold atomic absorption spectrometry after pre-enrichment was established. The influence of pre-enrichment and determination conditions on sensitivity was studied. Under the optimum operation conditions of determining trace mercury in 150 ml water sample, the quality was 0.01 ng/1%, the standard deviation (SD) ranged from 0.0008 to 0.001, and the recovery was 95.0% - 100.0%. The results were relatively satisfactory. |
