Abstract

The potential of waste rubber tires to adsorb heavy metals was investigated. Synthetic solutions of Cd(I1), Cr(111), and Pb(S) were used as the adsorbate and waste rubber tires pieces cut to 10 mesh size were wed as the adsorbent. Both the ached rubber and the supernatant solution were analyzed using atomic absorption spectroscopy (AAS). For all the metals wed, adsorption increases as concentration is increased from 0.001 M to 0.2 M, increases with increasing temperature ( 10, 25, 40 and 60°C ), and decreases with increasing acidity. Selectivity of heavy metal adsorption by waste rubber tire particles was found out to follow the order Cr3'>Cd2'>Pb2f. The adsorption isotherm was also established for each heavy metal. From the results, it was found out that rubber has the capacity to adsorb heavy metals, thus, can be utilized as heavy metal adsorbent.
