کارایی فرایند ازن زنی به همراه کلسیم پراکساید در حذف آنتی بیوتیک سیپروفلوکساسین از محیط های آبی

Background: advanced oxidation processes such as catalytic ozonation are efficient for the removal of antibiotics. calcium peroxide is one of the catalysts that can be used as a source of hydrogen peroxide.objective: the aim of this study was to determine the efficiency of ciprofloxacin removal by ozonation process with calcium peroxide from aqueous solutions.methods: this experimental study was conducted in hamadan university of medical sciences, 2013. the process consisted of ciprofloxacin with a concentration of 10-100 mg/l, ph=3-11 calcium peroxide with a concentration of 0-0.1 mg/l, 1 gr/min ozone (o3), and 30 min reaction time in a semiconductor reactor. findings: in the optimal condition, at ph 3, calcium peroxide 0.025 mg/l, o3 1 gr/min, and initial antibiotic concentration of 10 mg/l, 92% of ciprofloxacin was removed and 45% of chemical oxygen demand was reduced. conclusion: with regards to the results, the ozonation process with calcium peroxide can be suitable for removal of ciprofloxacin contamination.
