Abstract
The adsorptions of Cu2+ and Pb2+ ions from aqueous solutions were studied using a natural locally available clay
sample obtained from Sango area, Ilorin, Kwara State as adsorbent. The batch technique was employed and the
effect of pH on the adsorption processes was studied. The adsorptions of the metal ions were found to be
dependent on the pH at which the experiments were carried out. A greater affinity of the clay was observed for
Cu2+ than Pb2+ with maximum adsorption capacities being 944.8 mg/g and 702.6 mg/g respectively. The results
indicated that clay in its natural form can be used as an alternative in the treatment waters that are contaminated
with these metals.
