Background & Aims of the Study: Pharmaceuticals are considered as an emerging
environmental problem due to their continuous discharge and persistence to the aquatic
ecosystem even at low concentrations. The purpose of this research was the investigation of
advanced oxidation processes (Fenton and Fenton-like) efficiency for the removal of nonbeta
lactam Antibiotics of azithromycin and clarithromycin from synthetic wastewater.
Materials & Methods: In this laboratory scale study, samples of synthetic wastewater
were prepared from azithromycin and clarithromycin antibiotics. Concentration of samples
was 200 mg/L. Chemical oxygen demand (COD) index was selected as the parameter for
evaluation in this study. Fenton and Fenton-like oxidation processes were done on synthetic
wastewater of azithromycin and clarithromycin. In Fenton (Fe2+/H2O2) and Fenton-like
(Fe°/H2O2) processes the influence of pH, iron and hydrogen peroxide on the removal
efficiency of the antibiotics were studied and the optimum values for each parameter were
determined.
Results: The optimum condition for Fenton in removal of azithromycin and clarithromycin
were pH= 7 and 7, Fe2+ 0.45 mmol/L and 0.45 mmol/L, hydrogen peroxide 0.16 mmol/L
and 0.2 mmol/L, and contact time of 1 h and 1 h, respectively. The optimum condition for
Fenton-like in removal of clarithromycin and azithromycin were pH= 7 and 7, Fe0 0.3
mmol/L and 0.36 mmol/L, hydrogen peroxide 0.3 mmol/L and 0.38 mmol/L, contact time
of 30 min and 30 min.
Conclusions: The findings of this study demonstrate that the Fenton and Fenton-like
processes under optimum conditions can play an important role in the removal of
azithromycin and clarithromycin antibiotics from industrial wastewater
