Adsorptive Separation Studies of beta-Carotene from Methyl Ester Using Mesoporous Carbon Coated Monolith

Adsorption of beta-carotene on mesoporous carbon coated monolith (MCCM) from methyl ester as a solvent was investigated. Kinetics and thermodynamics parameters have been evaluated. Maximum beta-carotene adsorption capacity was 22.37 mg/g at 50 degrees c. Process followed Langmuir isotherm. The adsorption was endothermic and spontaneous. Contact time studies showed increase in adsorption capacity with increase in beta-carotene initial concentration and temperature. Pseudo-second-order model was applicable to the experimental data. The value of activation energy confirmed physical adsorption process.
