Abstract

Background: ANTIBIOTICs to treat an illness or as a growth promoter, to be consumed. A pharmaceutical composition in the form of original or metabolized in the aquatic environment, due to increased bacterial resistance is a concern. Various methods have been used to remove it. The advanced oxidation process due to the ease of use, economical and high performance have attracted a lot of attention. The purpose of this study was to investigate the role of cerium dioxide on process efficiency combined UV/AC+ZnO as an advanced oxidation process is the removal of cefazolin in the aquatic environment.Methods: This experimental study was done in batch reactor that has a one Liter volume. In this study effect of parameters such as initial pH (3-9), initial concentration of Cefazolin (20-200 mg/L), Modified photocatalyst concentration (20-100 mg/L), reaction time (10-60 min) and CEO2 dose (20-200 mg/L) was investigated. In this study use of low-pressure mercury lamp with a power of 55 watts in stainless case. The kinetic of process according to zero order, first order and second order kinetic was evaluated.Results: The results showed that the highest removal efficiency of ANTIBIOTICs cefazolin in the process at the pH=3, concentration 0.1 mg/L of Modified photocatalyst, Retention time of 60 min and Cefazolin concentrations of 100 mg/L was 96%. When you change any of the parameters of about optimization, process efficiency was renamed. The results also showed that by increasing the concentration of CEO2, the ANTIBIOTIC removal efficiency decreased, so that by increasing the concentration of CEO2 from 20 to 200 mg/L, the ANTIBIOTIC removal efficiency of cefazolin decreased from 91 to 76%.Conclusion: This process has shown high efficiency in removal cefazolin and the ability of this process to reduce the burden on hospital sewage and pollution-producing industries before entering the units and final discharge effluent also contains conventional treatment or used for cefazolin. This process, because of the lack of production waste such as sludge, a process persistent organic pollutants and significant in the treatment process is environmentally friendly.
