The feasibility of employing wood-bentonite clay composite material as a low-cost and effective adsorbent for removal of cations from
wastewater has been investigated. The wood-bentonite clay composites were prepared by a solution intercalation method. Results showed
that the percentage adsorption of Pb 2+ , Mg 2+ and Ca 2+ from the effluent water was 88.46, 81.12 and 95.76 % respectively, using 10 g/L of
the adsorbent. The desorbed wood-bentonite clay composites could be reused for adsorption of the cations.
