ActiveAir quality--Determination of nitrobenzene(mononitro and dinitro-compound)--Reduction by zinc-N-(1-Naphthyl) ethylene diamine dihydrochloride spectrophotometric method
空气质量 硝基苯类 (一硝基和二硝基化合物)的测定 锌还原-盐酸萘乙二胺分光光度法
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.
