Abstract
The efficiency of Amorphophallus Paeoniifolius Tuber Activated Carbon (APTAC) prepared from natural source for the removal of Acid Fuchsin (AF) dye from its aqueous solution is examined in this study. Batch mode experiments conducted in different concentrations, pH, adsorbent dose, contact time and temperatures were studied in adsorption characteristics of AF dye removal on APTAC. The equilibrium data were analyzed using Freundlich, Langmuir and Temkin isotherms. Langmuir adsorption isotherm gave a good fit to the experimental data. The results proved that APTAC has a good adsorption capacity towards AF dye removal. The pseudo first order and pseudo second order kinetics data were applied to the adsorption data. The kinetic data confirmed to the pseudo second order suggesting that the rate limiting step may be chemisorption. The thermodynamic quantities such as Gibbs free energy (ΔG0), Enthalpy (ΔH0) and Entropy (ΔS0) were evaluated. The negative value of ΔG0 and negative value of ΔH0obtained indicates the spontaneity and exothermic nature of the adsorption. The changes in value of entropy suggest that the adsorption process was favorable. According to the results APTAC treated as cheapest and available bio-adsorbent to remove toxic dyes from waste water. keywords: adsorption, acid fuchsin, amorphophallus paeiniifolius tuber, activated carbon, isotherms, kinetics and thermodynamics.
