“…To estimate whether the hydroxyl radical is the main removal factor of DCF, excessive t-butanol was added as the scavenger of the hydroxyl radical, which was produced during the reaction [30,31]. Appropriate amounts (10:1, 50:1, 100:1, and 1,000:1 molar ratios of scavengers (t-butanol) to DCF) were added to the solutions prior to the addition of H 2 O 2 .…”

The use of nanoscale zero-valent iron (nZVI) for the purification of contaminated water and soil was investigated for its high potential to remove subsurface contaminants. In this study, the mechanism of diclofenac (DCF) degradation by nZVI and the combined process of nZVI and hydrogen peroxide (H 2 O 2) are discussed. The results demonstrated that nZVI with acidic conditions had a certain degradation efficiency on DCF, with a removal rate about 30% in a 2-hour reaction at pH 5. The combined process of nZVI and H 2 O 2 could obviously remove DCF, with a removal rate greater than 90% in a 2-hour reaction at pH 5. In nZVI system, under acidic and aerobic conditions, Fe 2+ and H 2 O 2 can be generated to form a Fenton-like system. Meanwhile, the release of electrons from nZVI could promote the reductive dechlorination of DCF. In nZVI/H 2 O 2 system, the high removal rate of TOC was also showed the DCF mineralization by the Fenton-like oxidation.

Fenton Reagent for Organic Compound Removal in Wastewater

The improper treatment of wastewater has cost humanity a large amount of access to clean water. Treating wastewater, by definition, means to remove pollutants, either physically or chemically. A chemical method of treating wastewater, the Fenton process, was deemed useful for the job. It includes a solution-based reaction that produces radicals to oxidize and break pollutants down. Variations of the Fenton process, each with their unique method, have been developed to increase the process’s efficacy and efficiency further. Admittedly, however, the information on this subject is relatively few, when compared to other more recent methods of treatment. This paper aims to present and discuss a wide variety of information on the Fenton process and its derivatives, including Electro-Fenton, Sono-Fenton, and Photo-Fenton among others.

“…The produced hydroxyl radicals can non-selectively mineralize organic compounds rapidly due to the hydroxyl radicals highly oxidation potential (E 0 =+2.80 V) which next only to fluorine [12,13,14]. However, the classic Fenton reaction has some critical drawbacks such as iron sludge which requires further separation and causes the early termination of the reaction [15,16].…”
