Abstract	Removal of divalent lead from aqueous solution, a comparative study of six sorbents was carried out by batch as well as column processes. The order of lead removal capacities for these chemical adsorbents was found to be IRA > PTS> PAC > PLC > FeO(OH) > RH. This is probably due to several factors such as molecular size, molecular polarity, pH lead reactivity and retentivity, sorbent properties and environmental conditions. The leaching order should be reverse of the sorption order. The sorption of lead ions goes on increasing as their concentration decreases from 10 to 0.1 mg/l. Thus, the removal was about 20 % less than what it was in the batch process Leaching increases as the flow rate increases. Solution pH significantly affected the extent of contaminant removal.
