Fixed-bed column study for Cu (II) removal from aqueous solutions using rice husk based activated carbon
In this work, the adsorption potential of rice husk based activated carbon (RHAC) to remove Cu (II) from aqueous solution was investigated using fixed-bed adsorption column. The effects of inlet Cu (II) concentration (5-15 mg/l), feed flow rate (10-30 ml/min) and RHAC bed height (30-80 mm) on the breakthrough characteristics of the adsorption system were determined. The highest bed capacity of 34.56 mg/g was obtained using 10 mg/l inlet Cu (II) concentration, 80 mm bed height and 10 ml/min flow rate. The adsorption data were fitted to three well-established fixed-bed adsorption models namely, AdamBohart, Thomas and Yoon-Nelson models. The results fitted well to the Thomas and Yoon-Nelson models with correlation coefficient, R2 ≥ 0.96.
