Statistical Optimization of the Fenton Process for Treatment of Amoxicillin and Cloxacillin Antibiotic Aqueous Solution by Response Surface Methodology
Fenton treatment of amoxicillin and cloxacillin antibiotic aqueous solution was optimized using the central composite design (CCD) and response surface methodology (RSM). The optimum operating conditions which achieved 78.98, 72.96 and 81.18% removal of COD, TOC and NH3-N, respectively at pH 3...

| Summary: | Fenton treatment of amoxicillin and cloxacillin
antibiotic aqueous solution was optimized using the central
composite design (CCD) and response surface methodology
(RSM). The optimum operating conditions which achieved
78.98, 72.96 and 81.18% removal of COD, TOC and NH3-N,
respectively at pH 3 were H2O2/COD molar ratio 2.0, H2O2/Fe2+
molar ratio 76 and reaction time 90 min. Removal efficiency by
model prediction and experimental validation were in close
agreement (<0.4% error). Biodegradability (BOD5/COD ratio)
improved from zero to 0.33, indicating that the treated
antibiotic aqueous solution was amenable to biological
treatment. FTIR spectra indicated degradation of the
beta-lactam bond of the antibiotics. |
