N2 - The accumulation of heavy metal ions in living cells impairs the organ function of living creatures. So, needs to develop new materials with high efficiency of heavy metals removal from the environment. As part of this effort, here, synthesized magnetic inverse spinel iron oxide nanoparticles (MISFNPs) using a biogenic methodology. To synthesize the biogenic MISFNPs, we used the seed extract of Cnidiummonnieri (L.) Cuss (CLC) as a precursor. The prepared MISFNPs was characterized using PXRD, FT-IR, SEM-EDX, SEM, BET, AFM and XPS. We also investigated the size, surface area, structure and magnetic properties of MISFNPs. Additionally, magnetic property measurement system (MPMS) studies show that our prepared MISFNPs was superparamagnetic at room temperature. Further, we used the MISFNPs for the removal of Pb(II) and Cr(III) from aqueous solutions through batch studies. Batch adsorption studies revealed that Pb(II) and Cr(III) follow pseudo-second-order kinetics during adsorption onto the homogenous surface of MISFNPs. Besides, we also found that the adsorption of Pb(II) and Cr(III) on nanoparticles followed an endothermic process. Lastly, we concluded that MISFNPs synthesized by a green route is capable of recycling and removal of heavy metals without loss of its stability.
