β-carotene adsorption onto mesoporous carbon-coated monolith column: dynamic studies


Muhammad, and Khan, Moonis Ali and Abdullah, Luqman Chuah and Choong, Thomas Shean Yaw (2013) β-carotene adsorption onto mesoporous carbon-coated monolith column: dynamic studies. Chemical Engineering Communications, 200 (10). pp. 1322-1333. ISSN 0098-6445; ESSN: 1563-5201


β-carotene adsorption dynamics from isopropyl alcohol (IPA) solution onto a mesoporous carbon-coated monolith (MCCM) column was studied. Kinetics and mass transfer parameters were modeled. Thomas and Adams-Bohart models were applied to the experimental data obtained from dynamic studies. The effects of bed depth, flow rate, and influent concentration on breakthrough curves and adsorption capacity were investigated. The results showed that β-carotene equilibrium uptake increased with decreasing flow rate and increasing influent concentration. The optimum adsorption capacity (1.37 mg/g) was achieved at 20 mg/L initial β-carotene concentration, 47.5 cm bed height, and 1.0 mL/min flow rate. The time to attain breakthrough point decreased, while a sharp breakthrough curve was observed with increase in flow rate and influent concentration and a decrease in bed height.
