Investigation of amoxicillin removal from aqueous solution by Fenton and photocatalytic oxidation processes



Amoxicillin, antibiotic removal, chemical oxygen demand (COD), fenton oxidation, photocatalytic oxidation


This study aimed to investigate the removal of amoxicillin (AMO) antibiotic and chemical oxygen demand (COD) by Fenton (Fe2+/H2O2) and photocatalytic (UV-A/TiO2) oxidation processes in aqueous solution. In experiments, pH, antibiotic, Fe2+, H2O2, TiO2 concentrations and reaction time parameters were examined. In Fenton process, the removal efficiencies of initial AMO and COD concentrations were 83% and 66%, respectively. Fe2+/H2O2 molar ratio was determined as 1/15. In Photocatalytic process, AMO and COD removal efficiencies were 62% and 52%, respectively. The results indicated that these two processes may enhance the rate of AMO removal in polluted water and could be used as a preliminary treatment, alternative to existing treatment systems.
