Abstract: The potential use of waste tyre rubber granules (WTRG) for the batch adsorption of naphthalene from aqueous solutions was investigated. The effect of various operational variables such as contact time, initial naphthalene concentration, adsorbent dose, size of adsorbent particles, and temperature of solution on the adsorption capacity of WTRG was evaluated. The adsorption of naphthalene by WTRG was a fast kinetic process with an equilibrium contact time of 60 minutes. A low temperature (5oC), small adsorbent particle size (0.212mm) and higher adsorbent dosage favoured the adsorption process. Results of kinetic and isotherm studies revealed that adsorption of naphthalene was best described by the Lagergren pseudo-first order kinetic equation and Langmuir isotherm equations respectively. This study has demonstrated the suitability of WTRG for the removal of naphthalene from aqueous solution.
