Application Summary AI generated
This standard specifies a gas chromatographic method for determining the total concentration of nitro compounds in industrial wastewater. It is applied in environmental monitoring and compliance testing for factories, particularly those in chemical, pharmaceutical, or explosives manufacturing sectors, to assess pollutant levels in discharged process water. The method enables precise quantification of nitroaromatic and other nitro-containing organic pollutants for regulatory reporting and wastewater treatment control.
