Description
Summary:	The adsorption of phenol from aqueous solution using waste tire rubber granules (WTRG) was investigated in a batch system. The effect of various factors such as initial concentration of phenol, amount of adsorbent, size of adsorbent particles, pH and temperature of solution on the adsorption capacity of WTRG and percentage removal of phenol was studied. The equilibrium time for a phenol concentration of 700mg/l was obtained to be 60 minutes indicating fast adsorption. The percentage removal of phenol and adsorption capacity of WTRG increased from 20.5 to 40% and 5 to 10.6 mg/g respectively with decrease in particle size from 2.36 to 0.30mm. The adsorption capacity of WTRG was observed to decrease from 13.4 to 9.9 mg/g with increase in solution temperature from 5 to 45°C indicating that low temperatures favoured the adsorption of phenol. Maximum adsorption was recorded at a pH of 8.5 and an adsorbent dosage of 4g. Isotherm data were analysed using Langmuir and Freundlich isotherm models. The equilibrium data for phenol adsorption on WTRG was observed to fit Langmuir isotherm best with an R2 value of 0.995. [PUBLICATION ABSTRACT]
