Abstract
Presented study determined the photocatalytic treatment of phenol in aqueous medium using titania (TiO2) immobilized in activated carbon derived from charred Canarium ovatum Engl. nut shell through boil deposition method. Composite dosage, irradiation time, initial phenol concentration, and pH were varied to investigate how percent degradation of phenol would respond. The investigation showed that amongst all parameters, only pH has a significant effect to the photocatalytic degradation of phenol, wherein degradation increases as pH value decreases. Moreover, Design Expert® showed that 90.437% phenol degradation will be achieved using optimum values.
