“…The optimal CC-MIL-10-DCD-1000 catalyst and PMS oxidant concentrations for the three reactive dyes are determined and listed in Table S2. Compared with the degradation performance of other catalyst/PMS systems in real dyeing wastewater, 60 a lower concentration (0.3 g/L) of the as-synthesized CC-MIL-10-DCD-1000 catalyst with a lower concentration (0.6 g/L, i.e., 0.9 mM) of PMS oxidants achieved a higher rate (around 0.3 g/L) of dye degradation. Besides, loading on CC can facilitate the recycling and reuse of the catalysts in water bodies, constituting two significant advantages of this catalyst over other materials.…”

This study simulated actual dyeing wastewater in dyeing factories with three types of dyeing wastewaters from laboratory cotton fabric dyeing to investigate the effects of catalyst and oxidant peroxymonosulfate (PMS) concentrations, pH level, and temperature on dye degradation in wastewater and determine the optimal conditions for dyeing wastewater treatment accordingly. The results demonstrated that the optimal conditions varied with the reactive dyes. Specifically, the optimal oxidant PMS concentration for degrading Reactive Yellow and Reactive Blue was 0.6 g/L, and that for degrading Reactive Red was 0.4 g/L. The optimal pH level for degrading Reactive Red and Reactive Blue was around 7.0, and that for degrading Reactive Yellow was about 5.0. The activation energy of the degradation and the mineralization degree of the three dyes were also discussed. Reactive Blue showed greater activation energy (47.0 kJ/mol) and a higher mineralization degree (81% chemical oxygen demand removal) than the other two dyes under optimal disposal conditions. The Fe/N-codoped carbocatalyst loaded on carbon cloth exhibited desirable reusability and good stability for the degradation of the three dyes. Mechanisms involved in their degradation were analyzed through X-ray photoelectron spectroscopy, focusing on N species, Fe-N binding, and C=C and C–N active components in the Fe/N-codoped carbocatalyst. Electron paramagnetic resonance experiments demonstrated that both the radical and non-radical pathways were accountable for the degradation of the three dyes, primarily the non-radical pathway. This study may contribute to the application of activated PMS for practical dyeing wastewater treatment.

“…When NaHCO 3 present in the system, the pH value changes significantly from 6.00 to 8.90 The degradation efficiency and kinetic rates decreased to 21.5% and 4.90 Â 10 À3 min À1 , which are much lower than 40.6% and 1.09 Â 10 À2 min À1 at pH ¼ 10.0. Therefore, there must be other reasons for inhibition of efficiency caused by HCO 3 À and can be explained by Equations ( 11) and ( 12) (Alhamd et al 2021).…”

Based on these studies and the high efficiency of bimetallic iron-based materials, researchers have recently paid more and more attention to trimetallic iron-based materials to ensure multifunctional, excellent stable catalysts, and high efficiency (Awad et al 2019).…”

Magnetic nickel-copper ferrite (NixCuyFe2O4) nano-catalyst was synthesized by co-precipitation method, and it exhibited excellent ability for activating peroxydisulfate (PDS) in the degradation of ciprofloxacin (CIP). As-prepared Ni0.5Cu0.5Fe2O4 properties were characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscope equipped with an energy-dispersive X-ray (SEM-EDX), transmissions electron microscopy (TEM), N2 adsorption-desorption isotherm plot of Brunauer-Emmett-Teller (BET) and Barrett-Joyner-Halenda (BJH), vibrating sample magnetometer (VSM). The maximum degradation efficiency is 80.2% by using 0.500 g/L of Ni0.5Cu0.5Fe2O4 for activating 5.00 mmol/L of PDS to degrade CIP (20.0 mg/L) at 25 ± 2 °C for 50 min (pH = 6.00). The presence of interfering ions Cl−, NO3−, and HCO3− inhibited the reaction by producing reactive species with low oxidation potential, inducing the degradation efficiency decreased down to 60.0%, 58.1% and 21.5% respectively. Ni0.5Cu0.5Fe2O4 displayed great magnetic separation characteristic for the satisfactory magnetization saturation value is ∼8.6 emu/g. The degradation efficiency of recycled samples is no significant difference after using for three times, which is about 60%, indicating that Ni0.5Cu0.5Fe2O4 is a reusability catalyst in activating PDS for CIP degradation. This work might provide an efficient and promising approach to construct recyclable magnetic materials that can be used for wastewater treatment.

“…Compared with hydrogen peroxide, persulfate has more stable properties and also has more advantages in practical application. On the one hand, SO 4 À • as an electrophilic reagent is selectively responsible for the removal of organic compounds having electron-donating moieties over a wide pH range, in this way can radical consumption not be reduced by other non-target materials, and not only has higher stability in aqueous solution but also has stronger mineralization ability (Nasseh et al 2020;Alhamd et al 2021). On the other hand, SO 4 À • has a similar or even higher redox potential (E 0 SO 4 À • ¼ 2.5-3.1 V, while E 0 •OH ¼ 1.8-2.7 V), and has a longer half-life compared to •OH (t 1/2 SO 4 À • ≈ 30-40 μs, while t 1/2 •OH , 1 μs) (Wang et al 2022).…”

Nickle-copper ferrite (Ni0.5Cu0.5Fe2O4) supported on activated carbon (AC) (AC@Ni0.5Cu0.5Fe2O4) was synthesized and used as adsorbent, photocatalyst, and activator of peroxydisulfate (PDS) to realize the removal of ciprofloxacin (CIP). AC@Ni0.5Cu0.5Fe2O4 properties were characterized by scanning electron microscope equipped with energy-dispersive X-ray (SEM-EDX), X-ray diffraction (XRD), N2 adsorption-desorption isotherm plot of Brunauer-Emmett-Teller (BET) and Barrett-Joyner-Halenda (BJH), vibrating sample magnetometer (VSM). A rapid removal rate (94.30%) of CIP was achieved on AC@Ni0.5Cu0.5Fe2O4/PDS/UV system with the condition of catalyst dosage 0.30 g/L, initial pH 7.3, PDS addition 0.20 mM, CIP concentration 10 mg/L (200 mL), UV 28 W, in 30 min. Free radical quenching experiments indicate that reactive species of superoxide (·O2−), holes (h+), sulfate radicals (SO4−·) and hydroxyl radicals (·OH) were produced and all worked. The reusability test demonstrated that AC@Ni0.5Cu0.5Fe2O4 could be recycled 5 times with minimal performance reduction for the removal of CIP. The XRD and SEM of the after used AC@Ni0.5Cu0.5Fe2O4 did not change significantly, which further showed its stability and recyclability. This work might provide new insight into the application of AC@Ni0.5Cu0.5Fe2O4 in photocatalysis coupled with adsorption in peroxydisulfate assisted system and has high potential in CIP removal.
