ActiveDetermination of the chemical oxygen demand in industrial circulating cooling water—Permanganate index method
工业循环冷却水中化学需氧量（COD）的测定 高锰酸盐指数法
Application Summary AI generated
This standard specifies the permanganate index method for measuring chemical oxygen demand (COD) in industrial circulating cooling water. It is applied in industries such as petrochemical, power generation, and metallurgy to monitor organic pollutant levels in cooling water systems. The method helps assess water quality, control scaling and corrosion, and ensure compliance with discharge or reuse requirements.
