The study of photo Fenton oxidation for lead removal from simulated wastewater.

This study aims to examine the ability of Photo Fenton oxidation processes when they have been used to treat simulated wastewater (SWW). A batch photo-Fenton oxidation process had been achieved to eliminate lead ions from SWW. The experimentations were intended by a Response surface method experimental design comprising the consequence of the irradiation time (30-120 min.), hydrogen peroxide (25– 100 ppm), Ferrous sulfate (5-20 ppm), lead concentration (2-10 ppm), UV Lamp (7w) and pH (3–9) then examining the results by statistical programs. Then and at the best values of these conditions (120 min., 65 ppm of H2O2, 12.5 ppm of ferrous sulfate, 2 ppm of lead concentration, UV lamp 3 and, pH 9) at room temperature. The elimination efficiency of the Photo Fenton oxidation (78 %) under optimal conditions. The result showed that the Photo Fenton process is suitable for heavy metal removal from wastewater.
