Abstract

The application of the thermo-gas-titrimetric (TGT) technique for estimating the ammonia content in ammonium X-, Y- and L-type zeolites is described. The values of ammonia content in different zeolites determined by the TGT method are in good agreement with those obtained by other conventional methods. The use of the TGT method enables one to distinguish between the ammonium ions physically adsorbed and those exchanged by the zeolite. The details of this method and its specific advantage are described in detail.
