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

الملخص EN

This study investigated the removal of amoxicillin (AMO) antibiotic and chemical oxygen demand (COD) by Fenton (Fe²+/H₂O₂) and photocatalytic (UV-A/TiO₂) oxidation processes in aqueous solutions.

In experiments, pH, antibiotic, Fe, H₂O, TiO₂ concentrations and reaction time parameters were examined.

In the Fenton process, the removal efficiencies of initial AMO and COD concentrations were 83% and 66%, respectively.

The Fe²+/H₂O₂ molar ratio was determined as 1/15.

In the photocatalytic process, AMO and COD removal efficiencies were 62% and 52%, respectively.

The results indicate that these two processes may enhance the rate of AMO removal in polluted water and could be used as a preliminary treatment or as an alternative to existing treatment systems.
