ActiveAnalysis of water used in boiler and cooling system—Determination of phosphate, chloride, silicate, total alkalinity, phenolphthalein alkalinity, hardness and iron—Spectrophotometric detection by discrete analysis systems
锅炉用水和冷却水分析方法 磷酸盐、氯化物、硅酸盐、总碱度、酚酞碱度、硬度和铁的测定 基于间断分析系统的分光光度法
Application Summary AI generated
This standard specifies a spectrophotometric method using discrete analysis systems for the simultaneous determination of phosphate, chloride, silicate, total alkalinity, phenolphthalein alkalinity, hardness, and iron in boiler feedwater and cooling water. It is applied in thermal power plants, industrial boiler systems, and circulating cooling water systems to monitor water quality and prevent scaling, corrosion, and fouling. The method enables automated, high-throughput testing for routine water quality control and compliance with operational safety standards.
