Abstract

Present study deals with the adsorption of ammonia by bagasse fly ash. Equilibrium isotherms for the adsorption of ammonia on bagasse fly ash were analyzed by Langmuir, Freundlich, Langmuir- Freundlich, Compound, BET, Dubinin-Raduskevich isotherm models using linear regression technique. Dubinin-Raduskevich isotherm was found to best represent the data for ammonia adsorption on bagasse
fly ash. The corresponding affinity coefficient b was 1 · 10-11. The value of characteristic energy of the system was 6,17 kJ/mol. The limiting amounts of ammonia adsorbed by the solid correspond to a monolayer was 19,9 mg/g.
Keyword: adsorption, ash, sugar, ammonia, thermodynamics.
