The effects of various experimental parameters including initial Fe2+ and H2O2 concentrations, working pH, and contact time were studied through a batch experiment. The concentration of As(V) resulted from the photo-oxidation was determined by visible spectrophotometry method based on the formation of arsenate molybdate solution. The results of the research attributed noticeably that the As(III) could be oxidized through photo-Fenton process to form As(V) that was assigned by a considerable decline in the concentration. The maximal oxidation of As(III) with 10 mg L-1 of the concentration in 50 mL of the aqueous solution, that was about 85%, can be reached in the presence of Fe2+ 10-2 mole L-1, H2O2 5. 10-2 mole L-1 at the working pH 3 and within 3 h of the reaction time. It has been also detected that for reaching the permissible level (lower than 0.01 mg L-1 ), three stages of the photo-Fenton process were required.</p> </p></abstract><publication_date><month>11</month><day>26</day><year>2021</year></publication_date><pages><first_page>550</first_page><last_page>555</last_page></pages><publisher_item><identifier id_type="pii">gnest_03265</identifier></publisher_item><doi_data><doi>10.30955/gnj.003265</doi><timestamp>1714065055</timestamp><resource>https://journal.gnest.org/publication/gnest_03265</resource></doi_data></journal_article></journal></body></doi_batch> </div>
