“…For wastewater treatment, NiO is also widely used as an adsorbent for synthetic dyes. 26 For example, Riaz et al 26 reported that NiO nanoparticles prepared by a green hydrothermal method showed an effective adsorption toward methyl orange (MO) with a maximum adsorption capacity of 97.56 mg g À1 at pH 4. Furthermore, Song et al 27 revealed that NiO nanosheets have high adsorptive affinity toward brilliant red X-3B, Congo red and fuchsine acid with maximum adsorption capabilities of 30.4 mg g À1 , 35.15 mg g À1 and 22 mg g À1 , respectively.…”

“…Shehadeh et al [ 14 ] used the modified nickel oxide nanoparticles with diatomite for the adsorption of Basic Red 46. The NiO nanoparticles prepared by a green hydrothermal method and NiO nanobelts synthesized hydrothermally were utilized for the removal of dyes [ 15 , 16 ]_ENREF_15_ENREF_15. The modified NiO with sepiolite and Fe 3 O 4 to produce NiO/sepiolite and Fe 3 O 4 /NiO nanocomposites of high adsorption capacities were also applied for the removal of Congo Red from wastewater [ 17 , 18 ].…”

The rapid development of industries discharges huge amounts of wastewater that contain surface water. For this reason, we used NiO/polydopamine (NiO/PDA) nanocomposite as an efficient material for the removal of Methyl violet 2B from water. It was synthesized and then characterized by Fourier Transform Infrared (FT-IR) spectroscopy, X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX) analysis, Transmission Electron Microscopy (TEM), and Brunauer–Emmett–Teller (BET). The EDX analysis confirmed the presence of O, Ni, N, and C. The composite has an average particle size of 18 nm. Its surface area is 110.591 m2/g. It was found that the efficiency of dye removal by adsorption on NiO/PDA exceeded that of bare NiO. The adsorption capacity of NiO and NiO/PDA are 126 and 284 mg/g, respectively. The effects of adsorbent dose, dye concentration, and pH on the removal efficiency were examined. The efficiency increased with increasing the adsorbent dose and pH, but dropped from 85 to 73% within 30 min as the initial dye concentration was increased from 0.984 to 4.92 mg/L. Such a drop in the removal efficiency is due to the blocking of the surface-active sites of NiO/PDA, with the high population of dye molecules derived from the continuous increase in dye concentration. The adsorption results of the dye fitted well with the pseudo-second-order kinetics and Langmuir isotherm. The reusability data showed that NiO/PDA was stable across three adsorption–regeneration cycles, thus it can be considered a good recyclable and efficient adsorbent. Because of these results, it can be considered that this method can be applied for the treatment of wastewater.

“…9 Nanotechnology played an important role in various applications in recent years, and considerable attention has been drawn to the use of nanotechnology for waste water treatment because of it is high surface area, small size, large number of reactive sites and strong adsorption capability. 10 Nickel oxide nanoparticles (NiO NPs) have catalytic, antibacterial, properties and can also be used in injury care, solar cells, and gas sensors. 11 NiO have been reported as effective photocatalyst in slurry form for various organic pollutants such as crystal violet dye, 12 Rodamine B dye 13 Congo red, and nitrophenol.…”

Structural, optical and photodegradation performance of PVDF/PVA polymer blend doped with different concentration of NiO NPs were studied using casting technique method. The effect of adding NiO NPs on PVDF/PVA are investigated using X-ray Diffraction (XRD), High Resolution Transmission Electron Microscope (HRTEM), Fourier Transform Infrared-Attenuated Total Reflection (FTIR-ATR), Ultraviolet-Visible Spectroscopy (UV-Vis), and High Resolution Scanning Electron Microscope (HRSEM). XRD results showed that the addition of NiO NPs increase the crystallinity of PVDF/PVA. The appearance and shifting of bands in FTIR-ATR indicate the structural change in the PVDF/PVA with adding NiO NPs combined with decrease in the band gap of nanocomposite films compared to pure blend in UV-Vis confirmed the incorporation of NiO NPs in PVDF/PVA.
