Resumo
Batch sorption experiments were carried out to remove methylene blue from its aqueous solutions
using zeolite synthesized from fly ash as an adsorbent. Nearly 10 min of contact time are found to be
sufficient for the adsorption of dye to reach equilibrium. Equilibrium data have been analyzed using
Langmuir and Freundlich isotherms and the results were found to be well represented by the
Freundlich isotherm equation. Adsorption data were fitted to both Lagergren first-order and
pseudo-second-order kinetic models and the data were found to follow pseudo-second-order
kinetics. Thermodynamic calculations suggest that the adsorption of methylene blue on zeolite
synthesized from fly ash is spontaneous and exothermic reaction.
