4 | Description | Abstract | Fly ash was modified by chemical treatment with NaOH solutions of varying concentrations (4, 3, 2 and 1 M) and labeled SHFA-4, SHFA-3, SHFA-2, SHFA-1 respectively. All four forms of fly ash were tested as adsorbents for the removal of methylene Blue dye from aqueous solutions. The effect of contact time and concentration were investigated using a batch adsorption technique. The experimental data could best be described by the Freundlich isotherm and the dynamic data fit well with the pseudo-second-order kinetic model, which suggests that the adsorptions appeared to be multilayer adsorption processes. Fly ash modified with 4 M NaOH (SHFA-4) demonstrated the highest adsorption capacity (KF=77.04 mg/L). The kinetic data confirms the applicability of the pseudo-second-order kinetic model which indicates multilayer adsorption processes. These results suggests that fly modified with NaOH could be employed as a low cost adsorbent for the removal of methylene blue form wastewater streams from textile, tanning and printing industries |
