ActiveDetermination of sulphuric acidmist in tail gas in sulphuric acid concentration process--Barium chromate colorimetric method
硫酸浓缩尾气硫酸雾的测定 铬酸钡比色法
Application Summary AI generated
This standard specifies the barium chromate colorimetric method for determining the concentration of sulfuric acid mist in tail gas emitted during the sulfuric acid concentration process. It is applied in chemical manufacturing facilities, particularly in plants that produce or concentrate sulfuric acid, to monitor and control air pollutant emissions from exhaust stacks. The method is used for environmental compliance testing and industrial hygiene assessments to ensure tail gas meets regulatory limits for sulfuric acid mist.
