ActiveDetermination of nitrite in the wet precipitation--N-(1-naphthyl)-1， 2-diaminoethane dihydrochloride spectrophotometry
大气降水中亚硝酸盐测定 N-(1-萘基)-乙二胺光度法
Application Summary AI generated
This standard specifies the N-(1-naphthyl)-1,2-diaminoethane dihydrochloride spectrophotometric method for determining nitrite concentrations in wet precipitation (e.g., rain, snow). It is applied in environmental monitoring and atmospheric chemistry studies to assess nitrite levels in atmospheric deposition, which helps evaluate air pollution impacts on water quality and ecosystems. The method is used by environmental laboratories and regulatory agencies for routine analysis of precipitation samples.
