Back­ground and Aim: Pharmaceuticals, especially antibiotics, are new contaminants that because of their cumulative nature, adverse effects and drug resistance; have created a major environmental concern. The aim of this study was to evaluate UV/peroxymonosulfate (UV/PMS) process efficiency in the removal of cefexime antibiotic from aqueous solution.
Materials and Methods: This experimental laboratory study was conducted in batch mode. We assessed the effects of main operational parameters such as solution pH (3-9), reaction time (0-30 min), photocatalyst dosage (0.75-2.25 mmol/L), and initial concentration of cefexime (5-25 mg/L) on removal efficiency. Spectrophotometer (HACH DR-5000 UV–Vis) was used to measure the initial and final concentrations of cefexime.
Results: Under optimal condition (pH=7.5, irradiation time=30 min, C0=5 mg/L, and PMS dosage=1.37 mmol/L), use of photocatalytic UV/peroxymonosulfate led to efficient removal of cefexime (93.18%).
Conclusion: The results of this study showed the acceptable performance of peroxymonosulfate process in the removal of cefexime.
Keywords: Advanced oxidation pocesses (AOPS), Peroxymonisulfate, Cefexime, Ultraviolet radiation (UV)
