Abstract
Advanced oxidation process is a technology used in detoxification of residual water containing organic pollutants in small and medium scales. Radiocatalysis is a process that combines photocatalysis and radiolysis. An important experimental parameter in radiocatalysis is the pH because it influences the electrochemical system by modifying the electric charge on the surface of materials. This effect was investigated in the radiocatalytic degradation of 4-chlorophenol using titanium, silicium, and aluminum oxides. It was found that the degradation of 4-chlorophenol is enhanced at pH between 3 and 7.
