Pure nickel ferrite nanoparticles (NiFe2O4 NPs) were prepared by the solvothermal method. Different concentrations of NiFe2O4 were added to PVDF/PEO blend to prepare the PVDF/PEO-NiFe2O4 nanocomposite films. The films were characterized using different techniques in detail. Pure NiFe2O4 NPs images have a semispherical shape and roundness of the edges, with average particle size ~ 4.3–8.8 nm, and polycrystalline structure. Pure NiFe2O4 NPs show that micrometrical agglomeration suggests the presence of pore-free crystallites on the surface. The spectroscopic techniques such as XRD, FTIR, and UV–visible have confirmed the interaction between PVDF/PEO and NiFe2O4 NPs. Still, the nanocomposites exhibit a smooth surface with typical spherulitic clusters revealing the semi-crystalline structure of the PVDF/PEO-NiFe2O4 nanocomposites. The values of ε′ and ε″ were increased as an increase of NiFe2O4 due to the high value of dielectric permittivity of NiFe2O4. The appearance of semi-circles in the plot of M″ with Log confirms the single phase of the samples. The dielectric measurements show that M′ is inversely proportional to ε′. At higher temperatures, M′ levels off at frequencies higher than those at lower temperatures because the relaxation processes were spread over a range of frequencies. The values of saturation magnetization of PVDF/PEO-NiFe2O4 films were linearly increased as an increase of NiFe2O4 indicates improvement in the magnetic vector arrangement. Due to the enhancement of the magnetic properties, they can further exploit the films for magnetic applications.

A novel Zn (II) organic framework comprising 2-phenyl benzimidazole (ZPBIF-1) was synthesized by using a solvothermal method. The characterization of the synthesized MOF was performed utilizing XRD, SEM, FT-IR, 1H-NMR, 13C-NMR, MS, XPS, TG/DTA, and N2 sorption analysis. ZPBIF-1 was successfully utilized to remove Acid red 88, Basic Violet 14, Basic Blue 54, and Congo red dyes in aqueous solutions. In this study, some parameters, including adsorbent dosage, initial dye concentration, contact time, temperature, and pH, were examined. To evaluate the experimental data, Freundlich, Langmuir, Temkin, and Dubinin-Radushkevich isotherm models were used. In this case, Langmuir is the most suitable model. Several kinetic models, including First-order, pseudo-first-order, second-order, and Pseudo-second-order kinetic models, Elovich's, and Weber's intraparticle diffusion models, were utilized to comprehend the detailed adsorption process. According to the pseudo-second-order kinetic model, dye sorption kinetics is best described. In addition, thermodynamic parameters like enthalpy (ΔH°), Gibbs free energy (ΔG°), and entropy (ΔS°) were also achieved and analyzed. The experimental studies thus suggest that Zn (II) metal–organic framework based on 2-phenyl benzimidazole could be a promising candidate for eliminating dyes from aqueous solution. Hence, the experimental studies suggest that a Zn (II) metal–organic framework based on 2-phenylbenzimidazole could be a promising candidate for eliminating dyes from aqueous solution. The maximum adsorption capacity of ZPBIF-1 was 1666.66, 1250, 1000, and 1250 mg/g for Acid red 88, Basic violet 14, Basic blue 54, and Congo red dyes, respectively. Furthermore, this method was used to remove contaminant dyes from textile wastewater, and an acceptable result was obtained.

“…The CR dye is a secondary organic di-azo dye with complex aromatic components that make the dye more persistent and non-degradable, making removal difficult [5,6]. Several physical, biological and chemical processes are available to remove colorants from industrial effluents, including electrochemical treatment, aerobic and anaerobic microbial degradation, and photochemical degradtion and ion exchange [7][8][9][10]. Nanoparticles such as Ni, Ag, Au, ZnO, CuO, CdO, NiO and others are effective in green-remediation and organic dye treatment of polluted water [11,12].…”

The catalytic activity of Ni NPs can be utilized to alleviate environment pollution caused by industrial effluents containing organic dyes. In the present work, a green method was employed for the synthesis of Nickel (Ni) nanoparticles using Polyphenolic rich Terminalia Chebula fruit aqueous extract and evaluated its catalytic activity against carcinogenic congo red dye along with antioxidant activity. The UV-Vis peak at 395 nm revealed the formation and monodispersed nature of nanoparticle. FTIR studies confirmed that polyphenolic and alkaloids were utilized in the formation of nanoparticles. The XRD established formation of Ni nanoparticles of FCC. SEM indicated the agglomeration of nanoparticles and TEM established the spherical shape with an average size about 6-8 nm. This study also evaluated the catalytic and antioxidant activities of green synthesized Ni NPs. Catalytic degradation of carcinogenic congo red dye completed within 20 mints, degradation of the congo red dye found to be first order kinetics, antioxidant activity against DPPH found maximum to 100 μg/ml and EC50 as 65.01.
