Adsorption of Basic Blue 12 From Cocoa (Theobroma Cacao) Shell Activated Carbon–Equilibrium Isotherm Analyses

Dr. S. Mylsamy

Abstract :

The ability of cocoa shell activated carbon (CSAC) was used to remove Basic blue 12 (BB12) dye from aqueous solution by adsorption have been studied. Equiliium isotherms for the adsorption of BB14 onto CSAC were measured experimentally. Results were analyzed by Langmuir, Freundlich, Tempkin and Harkin’s-Jura isotherm equations using a linearised correlation coefficient. The Langmuir isotherm gave the best correlation for the adsorption of BB12 onto CSAC. Thermodynamic parameters such as ΔH°, ΔS° and ΔG° were evaluated. The positive enthalpy shows that the adsorption process was endothermic in nature. The results show that CSAC holds a great potential in removal of BB12 dye from industrial wastewater.
