Abstract
This study investigates the oxidative treatment of Ibuprofen (IP), a widely used non-steroidal anti-inflammatory drug and recognized emerging contaminant, through the application of the Fenton process. Ibuprofen frequently enters aquatic environments due to improper disposal, incomplete metabolism, and inefficiencies in conventional wastewater treatment systems, posing risks to both ecosystems and human health. Given its persistence and bioactivity, advanced oxidation processes (AOPs), particularly the Fenton reaction utilizing hydrogen peroxide (H?O?) as an oxidant and ferrous ions (Fe²?) as a catalyst, were explored for effective degradation. The research focused on evaluating the influence of three key parameters—pH, oxidant concentration, and catalyst concentration—on the removal of Total Organic Carbon (TOC) as a proxy for organic pollutant degradation. Preliminary experiments confirmed that neither H?O? nor Fe²? alone could significantly reduce TOC; only their combination produced notable removal, validating the necessity of the full Fenton reagent. Comprehensive parametric studies revealed that the optimal conditions for TOC removal occurred at pH ~3, with an oxidant-to-catalyst (ox/cat) ratio of approximately 15, specifically at [Fe²?] = 0.078 mM and [H?O?] = 1.18 mM. Under these conditions, 80.4% of the TOC was removed within 24 hours. These results align well with previous studies on the Fenton treatment of other contaminants, though variation is expected due to differences in pollutant structure and reactivity.
