4DescriptionAbstract The present study aims at the utilization of wood based activated carbons for the effective removal of rhodamine B and congo red dyes from water. Freundlich, langmuir and Redlich-Peterson isotherm equations were applied to the equilibrium adsorption studies and the isotherm parameters were evaluated. The adsorptions were almost over within 360 minutes and the pseudo-second order rate model fits the experimental data well. pH of the dye solutions affect the adsorptions significantly and maximum adsorptions were found at low pH values. Dilute acetic acid is found to desorb much of the adsorbed dye molecules.
