Abstract
A batch removal of a basic dye (Methylene Blue) from wastewater, using economical adsorbents (produced from pyrolysis and activation of scrap tyres) was investigated in this study. The effect of temperature on the adsorption capacity has been established. These adsorbents were found to be efficient in adsorbing this dye from solution. The batch sorption kinetics can be described as a first order reaction. The rate constants for adsorption have been calculated. Thermodynamic parameters (DeltaGo, Kc) indicate the endothermic nature of the dye adsorption on activated carbon.
