title: [On the regeneration of transforming reagents in the spray method for the determination of ammonium concentration].
abstract: Aerosol method detecting low concentrations of ammonium involves passage of the analysed gas over crystal hydrate of iron nitrate with consequent registration of the aerosol obtained. The method is sensitive and precise due to direct correlation between concentration of the dispersed substance and ammonium level. For precise evaluation and its effectiveness, the crystal hydrate of iron nitrate should be kept over 55-65% nitric acid solution before the analysis.
