AbolishedAnalysis of water used in boiler and cooling system―Determination of chemical oxygen demand―Rapid method with potassium dichromate
锅炉用水和冷却水分析方法 化学耗氧量的测定 重铬酸钾快速法
Application Summary AI generated
This standard specifies a rapid method using potassium dichromate to determine the chemical oxygen demand (COD) in water used for boilers and cooling systems. It is applied in industrial settings, such as power plants and manufacturing facilities, to quickly assess organic pollution levels in recirculating cooling water and boiler feedwater. The method enables timely monitoring of water quality to prevent scaling, corrosion, and fouling in thermal equipment.
