Application Summary AI generated

This standard specifies a spectrophotometric method for determining the concentration of nitrobenzene compounds (mononitro and dinitro compounds) in ambient air. It is applied in environmental monitoring and industrial hygiene contexts to assess air pollution levels, particularly in workplaces or areas near chemical manufacturing facilities where these compounds are produced or used. The method involves reducing the compounds with zinc and then measuring the color reaction with N-(1-Naphthyl) ethylene diamine dihydrochloride to quantify the pollutants.
