Wet chemical synthesis and a green synthesis approach have been used to produce magnesium oxide (MgO) nanoparticles. A floral extract of Madhuca longifolia(M. longifolia/mahua) was used as a reducing agent for magnesium nitrate hexahydrate and magnesium acetate tetrahydrate. Three different concentrations of floral extracts were used, along with two different concentrations of metal precursors. This study was designed to observe the influence of varying parameters on the particle size and shape of MgO nanoparticles. A Taguchi robust design approach was used to identify the factors that contribute most to the particle size and distribution of magnesium oxide nanoparticles, as well as the conditions that have the greatest impact. According to Taguchi analysis, the concentration of the metal precursor had the greatest influence on the size of the MgO nanoparticles. UV–visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDS), and X-ray powder diffraction (XRD) analyses were conducted to demonstrate the effective synthesis of MgO nanoparticles. The findings showed a variety of nanoparticle morphologies and a cubic crystal structure with high purity MgO nanoparticle content. Additionally, the FTIR analysis reveals that floral extracts were actively involved in the synthesis process. It was determined that the average size of all 12 samples ranged between 30 and 100 nm. To investigate the antimicrobial activity of synthesized MgO nanoparticles, Escherichia coliand Staphylococcus aureuswere used. The majority of the samples were found to be appropriately inhibitory against both microbial strains; average zones of inhibition were also noted, along with the determination of the best sample’s minimum inhibitory concentration for both microorganisms. This is the first attempt to explore the effects of different factors on the structural morphology of MgO nanoparticles using mahua flower extracts. |
