| Abstract: | The routine method of nitrite determination in seawater in “TheMarine Survey Norm” has been optimized in this paper, which will simplif y the operation processes and shorten the analytical time in order to adapt to t he demands of auto-determination under water. Besides, the stability of reagent s and nutrient standard stock solution has been studied in the determination of nitrite in seawater in situ for improving the preservation methods and prolongin g the service life of reagents to meet the long-time demands of auto-analyzer. |
