Introduction: The existence of pharmaceuticals in aquatic ecosystem, their persistence and possible effects on living organisms and inefficient systems in removal of these compounds from water and wastewater are a growing concern. In this research, the UV/TiO2 photocatalytic degradation of Cefixime was investigated so as to identify if this method was efficient for removal of Cefixime or not.
Methods: The experimental parameters like as primary concentration of Cefixime, catalyst dosage, solution pH and time were assessed and optimized. The photocatalytic analysis was based on residual Cefixime identification by HPLC. The chromatographic conditions were comprised of a reversed‐phase C18 column with mobile phase consisting of 45:55 v/v mixture of Acetonitrile: water.
Results: The optimum removal efficiency for Cefixime was obtained after 60 min (90.98%) when 1 mg/L TiO2 was used at pH=3. The increase of catalyst concentration from 1 to 70 mg/L led to a decrease in degradation efficiency.
Conclusion: According to results, UV/TiO2 process could be a promising technique for the removal of Cefixime with good efficiency in a relatively short reaction time
