“…Within the Fe(VI)/sulfite system, an emerging contaminant, namely N,N-diethyl-3-toluamide (DEET), was degraded at 78% in 10 s, and it was also observed that the presence of humic acid, Cl − , and HCO 3 − /CO 3 2− inhibited the oxidation of DEET [27]. Zhang et al [28] demonstrated the efficiency of the Fe(VI)/sulfite system to degrade a pollutant mixture in 30 s at pH 9.0, whereas Fe(VI) alone only achieved less than 6% removal. Sulfamethoxazole (5 µM), included in this mixture, was degraded at 70% with [Fe(VI)] = 50 µM and [sulfite] = 250 µM at pH 9.0 in 30 min.…”

“…The use of Fe(II)-Fe(III)/sulfite systems are, therefore, good candidates for their use in the detoxification of contaminated water [22][23][24][25][26][27][28][29][30]32,34]. Fe(0) represents an alternative as an activator in radicals generation [35], and the use of Fe(VI) and sulfite produces a synergic effect, speeding up the removal of contaminants [28]. The effectiveness of a degradation process in water treatment also implies that the degraded byproducts do not harm the environment.…”

This study is focused on advanced oxidation technologies (AOTs) using the combined effect of Fe(0–VI)/sulfite systems, that produce mainly SO4•− radicals, to remove different 4-aminobenzene sulfonamides (SAs), namely sulfamethazine, sulfadiazine, sulfamethizole, from aqueous solutions. Results obtained showed that neither sulfite nor iron alone is able to degrade SAs; however, the combined effect depends on the oxidation state of iron species whose effectiveness to activate sulfite to promote the degradation of SAs increased following this order: Fe(III) < Fe(II) < Fe(0) < Fe(VI). Using Fe(VI)/sulfite, the complete removal of SAs was obtained in 5 min largely surpassing the effectiveness of the other three systems. The sulfonamides’ removal percentage was markedly influenced by sulfite concentration and dissolved oxygen, which improved the generation of oxidant radicals. Response surface methodology was applied, and a quadratic polynomial model was obtained, which allowed us to determine the percentage of SAs degradation as a function of both the iron species and sulfite concentrations. The study of the influence of the water matrix on these AOTs revealed an inhibition of SAs’ removal percentage when using ground water. This is probably due to the presence of different anions, such as HCO3−, Cl−, and SO42− in relatively high concentrations. According to the byproducts identified, the proposed degradation pathways include hydroxylation, SO2 extrusion, and different bond-cleavage processes. Cytotoxicity of degradation byproducts, using MTS assay with HEK 293 and J774 cell lines for the first time, did not show an inhibition in cell proliferation, sustaining the safety of the process.

“…For this reason, several strategies have been proposed to improve the oxidation by ferrate. One of them is the use of sulfate-based radical precursors to produce reactive sulfate species which increase the mineralization extent (Feng et al 2019Shao et al 2019;Sun et al 2018;Zhang et al 2017). Thus, the combination of sulfite and ferrate leads to the formation sulfate and/or hydroxyl radicals (SO 4 •-, HO • ) which enhance the degradation efficiency of the target molecule Shao et al 2019;Sun et al 2018).…”

In this work, a new combination of oxidation treatments for the degradation of bisphenol A (BPA) is investigated. This innovative wastewater (WW) treatment includes the use of ferrate (FeO 4 2-) and its decomposition byproducts under dark and UVA irradiation. The oxidation by ferrate leads to a fast but incomplete degradation of BPA with a degradation extent of 45% after 60 minutes under adopted experimental conditions. However, the ferrate decomposition byproducts which are constituted by solid iron species can be used to further improve the pollutant degradation efficiency. Indeed, ferrate-mediated heterogeneous photo-Fenton process is employed for the first time to enhance the degradation of BPA. With respect to the application for wastewater treatment, UVA irradiation (which is part of solar light), non-toxic and natural origin compounds such as ascorbic acid (AA) and ethylenediamine-N,N'-disuccinic acid (EDDS) are used to design a sustainable process. Under optimized conditions, the degradation extent of BPA using this newly designed treatment reaches almost 100% with AA and 70% with EDDS. In order to assess the feasibility of this treatment, the ferratemediated photo-Fenton process is applied to treat municipal wastewater. The obtained results in WW are highly encouraging since a maximum BPA degradation extent of 63% and 60% is observed after 300 min by using AA and EDDS, respectively.

BACKGROUND: Emerging micro-pollutants (EMPs) in water have received much attention due to their potential hazards to human health and ecological security. Ferrate has been researched in recent years to remove both particulate and dissolved impurities (including EMPs) from water, and its promising performance has been attributed to the high oxidation capacity and coagulation functions. However, limited research has compared ferrate with coagulation alone in the treatment of EMPs, which is one of the major objectives of this study. RESULTS: Three emerging micro-pollutants (EMPs), imidacloprid (IMP), bisphenol-S (BS), and azithromycin (AZM) were chosen for this study. In all cases, ferrate outperformed to ferric chloride in the removal of the EMPs. For a given ferrate dose of 0.05 mM, 99% of BS, 85% of AZM, and 78% of IMP were removed for a start concentration of 10 ∼g L −1. However, if the start concentration was 1000 ∼g L −1 , removal efficiency was decreased to 82% for BS, 62% for AZM, and 22% for IMP. pH 5 was favorable to the EMP removal by ferrate for the study conditions. Although higher removals of IMP, BS, and AZM were achieved by ferrate in comparison to those by ferric chloride, only 20% DOC removal was achieved by the ferrate. The formation of various oxidation products in the degradation process resulted in the disparity of the solution toxicity; that of BS was reduced but those of IMP and AZM increased after ferrate treatment. Nevertheless, the toxicity of ferric chloride treated samples was all increased. CONCLUSION: Ferrate has higher efficiency comparing with FeCl 3 to remove IMP, BS, and AZM. Degradation of the EMPs by ferrate was more efficient in acidic conditions (pH 5) and at the EMPs' lower initial concentrations for the given conditions. IMP was more resistant to the ferrate treatment compared to BS and AZM under the same conditions. Overall, 20% DOC reduction was achieved by ferrate for pH 5. Finally, the toxicity of BS can be reduced but those of IMP and AZM were increased after ferrate treatment, whilst the toxicity of ferric chloride treated samples was all increased.
