Facile Synthesis of Iron Oxide Nanoparticles Using Lawsonia inermis Extract and Its Application in Decolorization of Dye

Metal nanoparticles are being used in various fields of science and technology; hence, concern of environmental safety during the production has also gained attention. Chemical and physical methods of metal nanoparticle synthesis are frequently practiced which involve toxic chemicals. Hence, alternative ecofriendly method for nanoparticle synthesis are required. In the current study iron oxide, nanoparticles were synthesized by the extract of Lawsonia inermis (henna) leaves. The synthesized nanoparticles were characterized by UV-Vis spectroscopy, scanning electron microscopy (SEM), and Fourier transform infrared Spectroscopy (FTIR). The synthesized iron oxide nanoparticles were showing significant magnetic property. The nanoparticles were found to exhibit nanorod-shape morphology. The synthesized nanoparticles has been used as agent to adsorb and remove the organic dye methylene blue. The removal efficiency for methylene blue (MB) was found to be 95%. Thus, these nanoparticles could be used as a remarkable adsorbent material for bioremediation of toxic dyes from water effluents.
