摘　　要：建立了一种预富集-冷原子吸收光谱法测定水中的痕量汞的方法,研究了预富集条件、测定条件等对灵敏度的影响。在最佳的条件下,用这个方法测定水样中的痕量汞,150ml样品中,特征质量为0．01ng／1％,标准偏差为0．0008- 0．001．回收率为95．0％-100．0％,结果较为满意。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/l%, the standard deviation （SD） ranged from 0.0008 to 0.001, and the recovery was 95.0% - 100.0%. The results were relatively satisfactory.
