| Abstract: | The problems about determination of nitrate in seawater with cadmium reduction method in GB 17378.4-2007 were analyzed and discussed. The results showed the determination and formula of nitrate in GB 17378.4-2007 had defect. Contrary to the problems, the improved method and modified formula were proposed, which made the determination of nitrate in seawater simpler, faster and more accurate. |
