U radu su ispitivane adsorpcione mogućnosti NH4ZSM-5 i HZSM-5 zeolita (grupa MFI, proizvod kompanije
Zeolyst International, USA) za maslačnu kiselinu i za amonijak iz vodenog rastvora. Dobijene adsorpcione krive za
amonijak prolaze kroz više platoa, što ukazuje na višeslojnu adsorpciju, dok se adsorpcija maslačne kiseline dešava
u monosloju (Langmuirov tip adsorpcione izoterme). Rezultati pokazuju da je adsorpcija, kako amonijaka tako i
maslačne kiseline jače izražena na modifikovanoj formi – HZSM-5 zeolitu.
This study has examined adsorptive characteristics of NH4ZSM-5 and HZSM-5 zeolites (group MFI, product of the
Zeolyst International company, USA) both of butyric acid and ammonia from the water solution. The obtained
adsorption curves for ammonia go through several plateaus, which indicates multi-layer adsorption, while the
adsorption of butyric acid occurs in mono-layer (Langmuir type of adsorption isotherm). The results indicate that the
adsorption, both of ammonia and butyric acid, is more distinct on the modified form-HZSM-5 zeolite.
