AbolishedAir quality--Determination of ammonia--Sodium salicylate-sodium hypochlorite spectrophotometric method
空气质量 氨的测定 次氯酸钠-水杨酸分光光度法
Application Summary AI generated
This standard specifies a spectrophotometric method for determining ammonia concentration in ambient air using sodium salicylate and sodium hypochlorite as reagents. It is applied in environmental monitoring and industrial hygiene contexts to assess air quality, particularly for detecting ammonia emissions from sources like chemical plants, livestock farms, and waste treatment facilities. The method is suitable for field sampling and laboratory analysis to ensure compliance with air quality regulations.
