Abstract
This research evaluated using inorganic adsorbents for removal of metals from solution. Batch experiments were carried out to determine the effects of adsorbent dosage, initial metal concentration and agitation time on metal removal. The results showed increasing metal ion removal with increasing adsorbent dosage, metal concentration and agitation time. Removal efficiencies of Al3+ and Mn2+ were reported at above 99% and 98%. Kinetic studies showed that the three adsorbents data on both Al3+ and Mn2+ removal were pertaining to pseudo-first-order and second-order kinetics and had a good fit to Elovich indicating that the adsorption rate-limiting step could be inferred as chemical sorption.
