| The adsorption and photocatalytic degradation of phenol in water in a batch photoreactor was investigated using TiO2/ACF preparaed by coating technique as photocatalyst. A 15W UV lamp (254nm) and a 300W high pressure Hg-lamp (365nm) were used as light source, respectively. The effects of some factors such as temperature, initial concentration of phenol, initial pH and calcium ion on adsorption and photocatalytic degradation were studied. The conditions of deep mineralization of phenol were also studied. The results showed that:The classical model of Langmuir gived a good description of the adsorption of phenol on TiO2/ACF, while the photocatalytic reaction followed the pseudo first-order kinetics. The adsorption enhanced the photocatalytic removal of phenol. The temperature and initial concentration of phenol had a great effect on adsorption and photocatalysis. Low temperature could improve the adsorption of phenol on TiCVACF photocatalyst, while increasing temperature could increase the photocatalytic degradation rate of phenol. With the increasing initial concentration of phenol in solution, the rates of adsorption and photocatalysis increased. Acid medium and calcium favored the adsorption and photocatalysis of phenol. Increasing light intensity and/or light source with short wavelength could enhance photocatalysis of phenol. And the addition of the small amount of hydrogen peroxide could make phenol degrade quickly and mineralize deeply under 254nm irradiation.
