In this work, an aqueous solution of the antibiotic chloramphenicol was treated by photolysis and an advanced oxidation process using hydrogen peroxide combined with UVC and solar radiation. In this system, a reactor containing three UVC lamps (30W) was used. A factorial plan 2² was designed with the following variables: time and a concentration of hydrogen peroxide and evaluated using the percentage of chloramphenicol degradation as the response. Twelve hours of exhibition to UVC and solar radiation obtained 83 and 21% of chloramphenicol degradation, respectively. When H2O2/UV was used, 98 and 5% of degradation were obtained after one and a half hours of exhibition to UVC and solar radiation with 3 mmol L-1 of hydrogen peroxide. The time-based kinetic constant was calculated as 6.3 x 10-2 min-1 with r2 equal to 0.9878. [ABSTRACT FROM AUTHOR] |
