Activated carbon prepared from Thevetia peruviana wood was used as an adsorbent for the removal of Acid Violet 49 from aqueous solutions. Batch adsorption experiments were performed for adsorption kinetics and isotherm by varying temperature, initial dye concentration, pH and time. The amount of dye adsorbed increased while increasing the initial concentration and temperature of the solution. The experimental data fitted well to Pseudo second order kinetic model with Intra particle diffusion as the rate determining step. Adsorption data fitted with Langmuir model. The negative value of Gibb’s free energy (?G°) indicated that the adsorption was spontaneous in nature. The results showed that the activated carbon of Thevetia peruviana was suitable for the removal of the acidic dyes from the aqueous solutions. The positive value of enthalpy ( ) indicated that the adsorption of the selected dyes were endothermic.
