Description
A granular adsorbent consisting of iron oxide particles cemented by a binding material was investigated for its ability to remove lead ion from water using both batch and column experimental methods. Results showed the optimum pH for removal to be between 5 and 7. Both batch and column studies yielded similar values for the binding constant–about 5-but column studies indicated a significantly larger capacity, with a value of 4.3 mg Pb/g of adsorbent. Regeneration of the sorbent can be achieved by flushing with an acidic solution (pH = 3), although for long adsorption runs some buildup of residual lead within the pores is possible as a result of incomplete desorption. Includes 27 references, table, figures.
