“…The high-resolution C 1s spectra consist of three peaks at binding energies of 284.8, 286.8, and 288.3 eV, assigned to the surface adventitious carbon or defect-containing sp 2 hybridized carbon atoms, C–NC bonding in the aromatic ring of g -C 3 N 4 units, and the sp 3 hybridized C–N bonding, respectively . The high-resolution N 1s spectra can be deconvoluted into three peaks at binding energies of 398.8, 400.6, and 401.5 eV, corresponding to the pyridinic-like N, pyrrolic-like N, and graphitic-like N, respectively. − …”

This work studies the use of Fe/Ni-MOFs for the removal of ciprofloxacin (CIP) in wastewater. Fe/Ni-MOFs are prepared by the solvothermal method and characterized by X-ray diffraction (XRD), a scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), and a thermal gravimetric analyzer (TG). Under the conditions of the concentration of 50 ppm, a mass of 30 mg, and a temperature of 30 °C, the maximum adsorption capacity of ciprofloxacin removal within 5 h was 232.1 mg/g. The maximum removal rate was 94.8% when 40 mg of the Fe/Ni-MOFs was added to the solution of 10 ppm ciprofloxacin. According to the pseudo-second-order (PSO) kinetic model, the R2 values were all greater than 0.99, which proved that the adsorption theory of ciprofloxacin by Fe/Ni-MOFs was consistent with the practice. The adsorption results were mainly affected by solution pH and static electricity, as well as other factors. The Freundlich isotherm model characterized the adsorption of ciprofloxacin by Fe/Ni-MOFs as multilayer adsorption. The above results indicated that Fe/Ni-MOFs were effective in the practical application of ciprofloxacin removal.

“…The characteristics of this stage are the endothermic peaks at around 771 °C and 842 °C on the DSC curve, as well as the exothermic peak at around 860 °C, with a weight loss of approximately 7.5%. Elemental and valence state information of ZnFe 2 O 4 /Ba 0.7 Sr 0.3 TiO 3 was analyzed using X-ray photoelectron spectroscopy (XPS) [25,30]. As shown in Figure 4a, the highresolution spectrum of Ba 3d exhibits two peaks at 794.21 eV and 779.21 eV, corresponding to the Ba 3d 3/2 and Ba 3d 5/2 electrons, respectively.…”

The use of photocatalytic technology to degrade polyacrylamide in crude oil extraction wastewater is a promising approach, but there have been few reports so far. In this study, ZnFe2O4/Ba0.7Sr0.3TiO3 heterogeneous composite materials of a spinel/perovskite type with different proportions were synthesized. The composite materials with 31% ZnFe2O4 content exhibited a maximum polyacrylamide degradation efficiency of 46.54%, which demonstrated the unique role of the spinel/perovskite heterogeneous structure. When Ag nanoparticles were grown in situ on the surface of ZnFe2O4/Ba0.7Sr0.3TiO3, the photocatalytic degradation efficiency reached 81.28%. The main reason was that the introduction of Ag nanoparticles not only increased the active sites and enhanced light absorption capacity but also accelerated the separation of photo-generated charges. This work provides new ideas for the construction of spinel/perovskite heterogeneous composite materials and has reference significance for the application of photocatalytic degradation in the treatment of wastewater-containing polymers.
