This research work goals at searching the effectiveness of Malachite Green dye removal using banana stem, an agricultural waste as an activated carbon. The banana stem activated carbon was made ready in the laboratory by carbonization followed by activation. Adsorption studies were carried out to check the effect of various experimental conditions like different pH values, varying contact time, initial concentration of dye and changing banana stem carbon dosage on the removal of Malachite Green dye from aqueous solution at constant Temperature and agitation speed. The equilibrium experimental data were used for applicability of Langmuir and Freundlich isotherm models and the kinetic models. Batch test showed that maximum of 99% of dye was removed when the dye concentration was 2 mg/L, at an adsorbent dose of 0.75 gm/L at dye pH 8 in 45 minutes. From the obtained results it is validated that the equilibrium data’s favorable for both Freundlich and Langmuir isotherms. Maximum adsorption capacity of banana stem carbon on malachite green dye was found to be 8.29 mg/g. It was prevailing that the adsorption process followed the pseudo-second-order rate kinetics. It was observed that intra particle diffusion is not the only rate-limiting step in this adsorption system but also regression results indicate that the linear regression model gives the best results. The above observations recommend that Banana stem carbon can be competently implemented for removal of malachite green dye from aqueous solution in the adsorption treatment processes. |
