Abstract
In the present study, investigation the performance of the photo Fenton process for treatment of wastewater pollutant with antibiotic tetracycline was conducted. The operational parameters that effluence the procedure (pH value of polluted water (3-10), the concentration of hydrogen peroxide (25-100 ppm), the concentration of ferrous Sulphate (5-20 ppm), the initial concentration of the antibiotic tetracycline (10-50 ppm), irradiation time (30-90 min), and the temperature (25-70 C°) on the removal of the tetracycline were studied. Minitab software by response surface method (RSM) Box-Bingham method was used to design the experiments and to discover the optimum conditions for determining a high efficiency of elimination the contaminated from the wastewater pollutant. The results showed that the degradation rate was 91.5% of the tetracycline antibiotic, and Optimum condition of (irradiation Time, pH value, initial Concentration of tetracycline, [ H2O2], [ Fe+2], and the Temperature were (90 min, 3, 15 ppm, 86.3 ppm, 20 ppm, 25C°) respectively. followed by analysis the results by Portable Statgraphics Centurion statistical software.
