“…Finally, analysis of the solutions obtained from the oxidation of BPA showed five by-products during the reaction: BPA-O-catechol (BPA-O-C), bisphenol-O-quinone (BPA-Q), 3-hydroxy-4-(2-hydroxypropan-2-yl) cyclohexa-3,5-diene-1,2-dione (3-H-4-2-HP-2-C-3,5-D-1,2-D), 4-hydroxyacetophenone (4-HAP), 4-isopropenylphenol (4-IPP), and hydroquinone (HQ). These products have been reported by other authors: BPA-O-C [63][64][65][66][67][68][69], BPA-Q [63,65], 4-IPP [20,64,[66][67][68]70,71], 4-HAP [20,63,64,[66][67][68]70],…”

“…From Figure b, it can be seen that the main peaks at 833.6 and 850.6 eV can be attributed to La 3d 5/2 and La 3d 3/2 of the trivalent state of the La ions, whereas the satellite peaks at 837.8 and 854.7 eV can be attributed to charge transfer from the ligand O 2p energy level to the La 4f energy level. The two major peaks at 724.2 and 710.3 eV with vibrational satellites at 718.6 eV found in the XPS spectra of Fe 2p in Figure c can be assigned to Fe 2p 1/2 and Fe 2p 3/2 , − indicating that both Fe and lanthanide ions are present in the chemical valence state +3. In addition to the different La, Fe, and O spectral lines, Figure d shows the C 1s signal, and the XPS spectrum can be divided into three sets of peaks, with the peaks located at 284.8 and 286 eV corresponding to the C–C bond and the oxygen-bound material produced from indeterminate carbon.…”

LaFeO 3 chalcocite precursor was prepared by solid-phase milling method, and LaFeO 3 -type chalcocite composite catalyst, referred to as LFCN catalyst, was synthesized by in situ doping of carbon and nitrogen (urea, melamine, dicyandiamide, and carbon powder), The catalytic performance of the catalysts was investigated by the different mass ratios of LaFeO 3 chalcocite precursor and carbon and nitrogen (1:1, 1:2, and 2:1) and the degradation mechanism. Various characterization analyses, such as Xray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Brunauer−Emmett− Teller (BET), showed that the doped composite LFCN catalysts exhibited a hemispherical network structure with a larger specific surface area than that of the pure phase LaFeO 3 material. In addition, the LaFeO 3 material adjusted the electronic structure of the original LaFeO 3 chalcogenide material to a certain extent after in situ doping with organic C and N elements, which enhanced its lattice oxygen oxidation ability. In the study of the catalytic degradation of sodium humate solution under natural light conditions, the catalytic performance was significantly improved compared to that of the pure phase LaFeO 3 , and 10 mg of the catalyst degraded 30 mg/L of sodium humate solution in 50 min, with a degradation rate increasing from 40 to 98%. The degradation rate increased from 40 to 98% after 4 applications, indicating that the LFCN catalyst has good stability and significant catalytic degradation performance.

“…However, one recent study focuses on photo-Fenton degradation of different micropollutants including BPS. Authors describe that complete degradation of BPS could be achieved under optimized conditions within 10–20 min . Further studies focusing on oxidative BPS degradation by means of UV + H 2 O 2 , UV + O 3 , or O 3 + H 2 O 2 have already shown earlier that • OH-based processes are suitable to degrade BPS in aqueous solutions. , However, investigations regarding BPS degradation are scarce.…”

Influences of pH, Reagent Dose, and Water Matrix Components on the Formation and Utilization of Hydroxyl Radicals in the Oxidation of Bisphenol S and para-Chlorobenzoic Acid by the Fenton Reaction

Factors influencing the efficiency of Fenton-based degradation processes are widely discussed in the literature, including the question of involved reactive species (i.e., reactive iron species such as ferryl vs hydroxyl radicals). The present study investigates the Fenton reaction in terms of degradation rates under different reaction conditions (i.e., reactant concentrations, pH, and presence of matrix constituents) using two model compounds (bisphenol S and para-chlorobenzoic acid). Fenton reaction was reported to require acidic conditions with an optimum at pH 3. However, the present study has shown that at very acidic pH (pH ≤ 2), the reduction of Fe(III) to Fe(II) is strongly hampered, lowering the efficiency of the Fenton reaction dramatically. Furthermore, the present study provides evidence that pollutants such as BPS can be degraded at pH 7 in the Fenton process, in the presence of Suwannee River NOM. This indicates that the Fenton reaction may indeed be applied for pollutant degradation at neutral pH.
