- Abstract
In this study, a facile green synthesis method was adopted for the fabrication of magnesium oxide nanoparticles (MgO-NPs) from Calotropis gigantea (Aak plant) root extract which acted as a capping and reducing agent. The fabricated MgO-NPs were characterized by UV-Vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR) and high resolution-scanning electron microscopy to determine optical, morphological and biological characteristics. UV-Vis spectra results showed an absorption peak at 317 nm whereas scanning electron microscopy showed spherical morphology of the synthesized MgO-NPs. FTIR spectra of the root extract confirmed the presence of phytochemicals, that is, amines, phenols, amides and ketones. Methylene blue (MB) dye was used as model contaminant to assess catalytic reduction potential of the synthesized MgO-NPs. Results obtained showed that biogenic MgO-NPs are suitable for catalytic reduction of MB dye and, when assembled in a sustainable manner, MgO-NPs have the potential to be used for the removal of toxic organic pollutants from industrial effluents.
