Nano-photocatalysis process is also one of theadvanced oxidation processes. This process is used for degradation of resistant organiccompounds. This study was carried out in order to investigate photocatalytic degradation ofthe antibiotic ciprofloxacin by zinc oxide nanoparticl e (ZnO) stabilized on a glass bed inaqueous solutions.Methods: This is an experimental study performed in the second half of 2015 at theEnvironmental Health Engineering Research Center of Korman University of MedicalSciences. Degradation of the antibiotic ciprofloxacinby ZnO was then investigated. Contacttime, the initial concentration of the antibiotic, pH and the amount of zno (the adsorbent)were the variables of interest. The experiments were conducted under optimal conditions ofremoval with a real solution of urban wastewater, whose quality had already been measured,followed by addition of antibiotic ciprofloxacin to it. The isotherm and kinetics of adsorptionwere then determined. Finally, data analysis was done through descriptive statistics' XRDanalysis indicated the crystal nature and purity of the nanoparticles.Results: The greatest removal efficiency for the antibiotic ciprofloxacin was obtainedfrom the aqueous solution at the optimal pH of 11, contact time of 90 min, and adsorbentvalue of 0.6 glL of zno stabilized on the bed along with the initial concentration of theantibiotic ciprofloxacin of 3 mglL. the degree of removal of this antibiotic under optimalconditions for the synthetic and real samples was obtaine d as 94.36 and 90.25Yo respectively'Evaluation of the linear models of the kinetics and adsorption isotherm revealed that the datafollow a pseudo-second order kinetic(R2=0.956). Thermo dynamic studieson the ZnO is an exothermic process.equation (R2:0.986) along with Freundlich isothermshowed that adsorption of the antibiotic ciprofloxacinConclusion: The nano-photocatalytic process with ZnO stabilized on a glass bedenjoys a relatively high efficiency in removing the antibiotic ciprofloxacin from aqueoussolutions, which can be used for such purposes'Keywo rds : nano-photocatalyst, ciprofl oxac in, zno, stabilization, glass
