| Abstract: | Trace mercury in seawater was directly determined with DMA - 80 Automatic Mercury Analyzer. Optimization on the choice of analytical condition, such as dry time, decomposition temperature and reduction temperature were elaborated. The result showed that the technique was in a good linear relation in the range between 0.4 -400 ng and the detection limits 2 × 10^-5 mg/L, The technique is easy to use with high sensitivity and accuracy. |
