Environment-friendly synthesis of Ni_0.5Zn_0.5Fe₂O₄ magnetic nanoparticles using Plantago major and its applications as an efficient and rapid adsorbent for removal of reactive blue 21 dye

The Ni0.5Zn0.5Fe2O4 magnetic nanoparticles (MNPs) were synthesised using Plantago major seed extract through an environment-friendly, economic, and easy procedure. The nanoparticles were characterised by FTIR, XRD, SEM, TEM, EDX, BET surface area analysis, and VSM. The Ni0.5Zn0.5Fe2O4 MNPs were investigated as a nanoadsorbent for removal of reactive blue 21 (RB 21) and the results showed that the nanoparticles were effective for adsorption of RB...
