The routine method of nitrate determination in seawater in “Marine Survey Criterion” has been optimized and a method with mixed reagents of sulfonamide and α-naphlthyl elthyl diamine was developed.The cadmium-copper reduction column，the stability of reagents and nutrient standard stock solution were studied in the determination of nitrate in seawater in situ for improving the preservation methods and prolonging the service life of reagents to meet the long-time demands of auto-analyzer.
