In this work, experiments were conducted to explore the potential of saw dust activated with hydrochloric acid (ASD) as adsorbent for methylene blue (MB) removal. The influence of different variables like solution pH, MB concentration, contact period and ASD dosage were studied. Adsorption data were better fitted to the second order kinetics. Experimental equilibrium data were analyzed by various established isotherms and Langmuir isotherm was found to be better fitted one. Thermodynamic parameters like Gibbs free energy (G), change in enthalpy (H) and entropy (S) were estimated and the adsorption of MB onto ASD was found to be exothermic and favorably influenced by decrease in the temperature. A mathematical model for MB transported by molecular diffusion from the solution to the surface of ASD was derived and the values of liquid phase diffusivity and external mass transfer coefficient were estimated.
