This work evaluates the photocatalytic activity of bare TiO2 and TiO2 immobilized on activated carbon (TiO2/AC) for degradation of pharmaceuticals. Four selected pharmaceuticals namely amoxicillin, ampicillin, diclofenac, and paracetamol were oxidized using solar irradiation. The TiO2/AC composite was prepared by a temperature impregnation method. Characterization of TiO2/AC by Brunauer–Emmett–Teller (BET) analysis, Fourier transforms infrared spectroscopy (FTIR), and scanning electron microscope (SEM) revealed successful immobilization of TiO2 particles on activated carbon. Amoxicillin and ampicillin were completely degraded by TiO2/AC, while 89% of amoxicillin and 83% of ampicillin were removed by bare TiO2. Likely, TiO2/AC attained higher removal of diclofenac (85%) and paracetamol (70%) as compared to bare TiO2. Amortization and operating costs of full scale solar photocatalytic reactor were estimated. It was found that TiO2/AC is more economic.
