Abstract
The adsorption of ethylbenzene from aqueous solution using waste tyre rubber granules (WTRG) was investigated in a batch system. The effect of various factors such as contact time, initial concentration of eth ylbenzene, amount of adsorbent, size of adsorbent particles, and temperature of solution on the adsorption capacity of WTRG was determined. The equilibrium contact time was obtained to be 70 minutes indicating fast adsorption. The adsorption of ethylbenzen e on WTRG was observed to increase from 8.4 to 57.85 mg/g with increase in initial ethylbenzene concentration from 250 to 850 mg/L. The adsorption capacity of WTRG increased from 55.35 to 71.6 mg/g with decrease in particle size from 2.36 to 0.212mm. Incre asing the temperature of the aqueous solution from 5 to 40 o
