Gas volumetric determination of ammonium ions in ammonium salts
Forschungsinstitut für Celluloseindustrie in Bratislava
Abstract: The method and app. for gas volumetric detn. of NH4+ in NH4 salts, replacing distn. and oxidimetric method, are described. The principle of this method is oxidation of NH4+ by NaOBr on elementary N, the vol. of which is measured in a special app. The presence of reducing matter, which can be easily eliminated, does not disturb the detn. Formation of N by oxidation occurs rapidly, so that only a few min. is required for the detn.
