The experimental study on photocatalytic phenol removal was conducted by using TiO_(2) as a photocatalyst and ultraviolet(UV) ray as a light source. The effect of several variables such as the amount of photocatalyst, the wavelength of UV ray and the operation temperature and pH of reaction system on the removal efficiency of phenol was experimentally examined. Up to the concentration of photocatalyst 0.025g/L, the removal efficiency of phenol increased with the concentration of photocatalyst and beyond this concentration the reaction rate was independent of catalyst concentration. The removal of phenol was enhanced as the energy intensity was increased, that is the wavelength became shorter. It seemed that the photocatalytic decomposition of phenol prefers the basic condition and is insensitive to the operation temperature.
