<p><span style="font-size:14px"><span style="font-family:Arial,Helvetica,sans-serif">An investigation into the adsorption potential of activated and unactivated waste tyre powders for some heavy metals (Pb²⁺ and Cd²⁺) in their aqueous solution has been studied. The result indicated that unactivated waste tyre is a good non-conventional adsorbent for the removal of Cd²⁺ from aqueous solution. A total of 93.3% of cadmium, contents was removed. The unactivated waste type proved a good absorbent for the removal of Cd²⁺ 5g of 500&micro;m activated tyre removed over 86.66% of Pb²⁺ from solution.</span></span></p>
