The photocatalytic degradation of ciprofloxacin (designated as CIP) under UV-A irradiation is used to evaluate the performance of TiO2 and the synthesized photocatalysts. A irradiation time of 2 hours with a mean intensity of 200 ± 20 lx and a temperature of 27°C is used in the conduct of experiments. The volume is 200 mL of 10 mg/L, 20 mg/L, and 30 mg/L pollutant concentration (CIP) and the catalyst loading is chosen as 1 g/L. The samples are kept in the dark for 60 minutes to attain complete adsorption before starting the illumination. Liquid samples are taken at regular time intervals and filtered & centrifuged to remove the solid catalyst particles.
