The removal of Ibuprofen antibiotics (IBU) by photo-degradation UV/H2O2/Fe+2 system was investigated in a batch reactor under different initial concentrations of H2O2 (100-500) mg/L, Fe+2 (10-40) mg/L, pH (3-9) and initial concentrations of IBU (10-80) mg/L, and their relationship with the degradation efficiency were studied. The result demonstrated that the maximum elimination of IBU was 85.54% achieved at 300 mg/L of H2O2, 30 mg/L of Fe+2, pH=3, and irradiation time of 150 min, for 10 mg/L of IBU. The results have shown that the oxidation reagent H2O2 plays a very important role in IBU degradation.

“…In a survey conducted by Safa and Mehrasbi, the observations showed that, the TOC removal percentage was lower than the COD removal percentage. 39 And in another study conducted by Aljuboury et al, COD and TOC removal percentages were found to be 64 and 78%, respectively. 11 In 2021, research was conducted by Mohadesi and colleagues, and under optimal conditions, COD removal was reported as 77.08%.…”

“…The highest percentage of COD removal was observed at a pH of 3. 39 The results indicate that COD and TOC removal efficiency decrease with increasing pH. This is because hydroxyl radicals are formed in larger quantities in an acidic environment.…”

Background: In the last few decades, concern over environmental safety has increased significantly. One of the main causes of environmental degradation is the discharge of untreated pollutants into water bodies. This study examined the efficiency of the photo-Fenton oxidation process to remove chemical oxygen demand (COD) and total organic carbon (TOC) from petroleum wastewater. Methods: Experiments were designed using the Box-Behnken method- a model of the response surface method (RSM) by MINITAB software. First, a wooden chamber equipped with UV lamps installed in the center was applied. The effect of effective parameters on the photo-Fenton process, including naphthalene concentration (10-70 μg/L), pH (2-7), H2 O2 (50-800 mg/L), Fe (5-80 mg/L), contact time (10-120 minutes) and UV rays was investigated. Results: The highest removal efficiency of the COD (case 89.27) was at achieved at pH=2, UV=24, naphthalene concentration 10 μg/L, Fe concentration 36.06 mg/L, hydrogen peroxide content 800 mg/L, and contact time 120 min. Besides, the highest removal efficiency of the process in removing TOC was 71.04% obtained at 2 pH=24, UV=24, and a reaction time of 120 min. Conclusion: Based on the results of this research, the photo-Fenton process has a significant efficiency in removing COD and TOC from petroleum effluents containing cyclic aromatic hydrocarbons and can be utilized as an efficient method for the treatment of petroleum wastewaters.

“…Despite the large number of studies using photo-Fenton or electro-Fenton oxidation to treat organics in aqueous solution or spiked soils, no study has reported their direct application in real contaminated soils. Both of these techniques were employed to treat the organic pollutants in soil extract in integration with soil washing of real contaminated soils (Huguenot et al, 2015;Safa and Mehrasbi, 2019;Villa et al, 2010). The readers are directed to Section 4.3 for further readings of this coupling.…”

“…The addition of oxidant after a preliminary reduction step could lead to the mineralization of the reduction by-products as the reactive oxidant species would react faster with low-chlorinated compounds or biphenyl, than with high-chlorinated compounds having greater stability (Rybnikova et al, 2016). oxidation has been successfully used as a post-treatment to decontaminate these contaminated effluents (Huguenot et al, 2015;Ma et al, 2016;Safa and Mehrasbi, 2019;Seo et al, 2015;Villa et al, 2010). For washing in historically contaminated soils, different extracting agents have been used like non-ionic surfactants (Dominguez et al, 2019;Huguenot et al, 2015;Ma et al, 2016;Seo et al, 2015;Villa et al, 2010), biosurfactant (Fanaei et al, 2020), cyclodextrins (Ma et al, 2016), and organic solvents (Usman et al, 2012).…”
