【 摘 要 】

The present study describes phenol adsorption on commercial active carbon (CAF)under alkaline conditions in the concentration range of 0.01 to 2.08 mmolL-1. Surface characterization has been performed by means of surfacearea measurements, IR spectroscopy and Boehm titration. The effect of temperatureon the adsorption equilibrium isotherm was investigated at 23, 30, 40, 50 and60 °C. The results showed that adsorption capacity decreased with increasingtemperature. The adsorption kinetics and the role of surface characteristicson the adsorption of phenol also discussed.
