Synthesis Of Magnetite Fe3O4 Nanoparticles for The Removal of Divalent Nickel Ions from Aqueous Media.

One of the environmental issues of the twenty-first century is the heavy metal pollution of water. Numerous techniques for eliminating heavy metal ions from water have been thoroughly researched. Since magnetite nanoparticle-based nanomaterials are widely used to remove heavy metals, this work examined the use of Fe3O4 nanoparticles to remove the Ni(Ⅱ) ion from an aqueous solution. Utilising FTIR, SEM, and XRD methods, the synthesised nanoparticle was described. The results of the batch studies demonstrated that Ni(Ⅱ) may be efficiently extracted from an aqueous solution using magnetite nanoparticles. Ni(Ⅱ) was removed in large proportion (94.24%) from its aqueous solution at pH = 6, starting with a with a metal ion concentration of 40 ppm, a nanoparticle dose of 0.4 g, a contact duration of 35 min, and a rpm of 180. The mechanism of Ni(Ⅱ) elimination was determined by applying the kinetic models. This finding might be helpful for removing Ni(Ⅱ) ions from wastewater.
