Dye-containing industrial effluents create major concern nowadays. To address the problem, magnetic nickel oxide nanoparticles (NONPs) were synthesized using the autopropagator combustion technique assisted by sucrose as fuel and used for the removal of toxic malachite green (MG) from water. The material was characterized by scanning electron microscopy (SEM–EDS), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), vibrating sample magnetism (VSM), point of zero charge (pH ZPC ), and Brunauer–Emmet–Teller surface area analysis. SEM images show flowerlike texture with the presence of multiple pores. VSM reveals a well-defined hysteresis at room temperature, confirming a permanent magnetic nature of the material. pH ZPC was found to be 6.63, which enables dye separation in the drinking water pH range. MG removal from water was carried out in the batch mode with optimized physicochemical parameters such as contact time, pH, temperature, and dose. Langmuir adsorption capacity was estimated to be 87.72 mg/g. Pseudo-second order kinetics ( R 2 = 0.999) and Langmuir isotherm model ( R 2 = 0.997) were found to best fit. The magnetic nature facilitates fast and quantitative separation of NONPs from solution using a hand-held magnet. Dye-loaded NONPs can be easily regenerated up to 89% and reused up to five cycles without significant loss of activity. The mechanism of adsorption is proposed to be a combination of electrostatic attraction and weak hydrogen bonding. Strategically designed straightforward synthetic protocol, low cost, high uptake capacity, and sustainable use render NONPs an ideal alternative for future dye treatment.

“…Alumina is also known to have pore system and active sites on its surface. Alumina was reported by several researchers for having the ability to adsorb orange G, yellow monochlorotriazine, and yellow dichlorotriazinecolor black G [5,[15][16]. Surface modification of adsorbent using alumina was expected to increase the adsorption capacity as shown by modification of bentonite-alumina [17], alumina-chitosan [18], and activated carbonalumina [19][20].…”

“…Zinc oxide (ZnO) is one such important metal oxide NP which has gained the scientific spotlight currently. The unique set of characteristics of ZnO NPs such as catalysis, medicinal effects, photochemical capability, fungicidal, antibacterial and UV filtration has made ZnO a multi-functional agent and more promising for wastewater remediation [5]. The aim of the present investigation is to study the adsorption isotherms of copper (II) and nickel (II) ions removal on commercial zinc oxide nanoparticles and also determine the thermodynamic parameters of adsorption process.…”

This present work done on the adsorption isotherm study for the removal of Cu (II) and Ni (II) ions from aqueous solution using industrial zinc oxide nanoparticles. Various techniques such as AFM, XRD and FT_IR were employed to characterize the surface. From the XRD analysis, each reflection peak with the relative intensity of different planes confirmed the presence of ZnO and the spectrum revealed that the particles size was about (27.43 nm ), which is in good agreement with those estimated from AFM and mean that the particle diameters are in the nanometer range. Adsorption experiments were studied to investigate the effect of contact time, adsorbent dose, initial concentration, and temperature on the adsorption capacity. The equilibrium data were evaluated by the Langmuir, Freundlich, Elovich and Halsey models of adsorption. The removal of Cu (II) and Ni (II) by ZnO nanoparticles follows the Freundlich and Halsey isotherm which fits well with the experimental data (R 2 = 0.9718, 0.9942, 0.9525 and 0.9941 respectively). The maximum percentages of Ni (II) and Cu (II) removal were found to be above 96.03 % and 96.45 % as well. Finally , the thermodynamic parameters (∆H, ∆S, ∆G o ) were calculated and indicated that the adsorption process is exothermic , spontaneous, and less random when metal ions overlap with the commercial zinc oxide nanoparticles. The higher percentage removal at higher dosage value of ZnO could be due to an increased active sites for the adsorption of metals ions with an increased amount of adsorbent dosage.
