Gallus domesticus eggshell was investigated for its ability to remove copper from aqueous solution in an up-flow packed column. The sorption performance of eggshell in the column was examined by varying the bed height (15-25cm) and flow rate (5-20ml/min). The column was regenerated using 0.01 M EDTA solution and sorption-desorption studies were carried out for five cycles. (c) 2004 Elsevier Ltd. All rights reserved.
