| Abstract | The aim of the present work was to investigate both the adsorption mechanism and adsorption kinetics of a cationic dye, methylene blue, onto rice husk from aqueous solution with respect to the initial dye concentration, temperature, pH, mixing rate and sorbent dosage. Equilibrium parameter has analyzed and it was found that Langmuir and Freundlich isotherm fit for all material but Freundlich fit better than other isotherm. The adsorption kinetics study shows adsorption mechanism follows pseudo second order kinetics mechanism. Thermodynamics standard Gibbs free energy (ΔG ̊) is negative which indicates parameter shows negative for all material it indicates adsorption is spontaneous while standard enthalpy (ΔH ̊) is negative shows that adsorption of methylene blue onto these material is exothermic. While positive value standard entropy (ΔS ̊) reflects the affinity of adsorbents for methylene blue. The main objective of the study was to remove methylene blue by using low cost adsorbent like rice husk and it was found this material can used as adsorbent for removal of methylene blue dye. |
