Carbon nanoparticles prepared from the flours of maize, millet and mustard
(UMT, Lhr, 2019) MAHAM ARIF
Carbon Nanoparticles were prepared through controlled heating the powders of Maize, Millet and Mustard in a muffle furnace at 350 ºC. The purification of carbon nanomaterials were carried out by dispersing it in the ethanol water mixture (1:5) and sonicating this dispersion for 30 minutes at 45 ºC. The dispersed material was allowed to settle down and decanted part was filtered through sintered glass crucible no. 3. The sintered glass crucible then dried in an oven at 60 ºC for two hours. The carbon soot obtained from the crucible was subjected to characterization through UV/Visible Spectroscopy, Powder X-Ray Diffraction (XRD), Thermo Gravimetric analysis (TGA), Differential Scanning Calorimetry (DSC), Scanning Electron Microscope (SEM) and Fourier Transform Infra-Red spectroscopy (FTIR). The average size of prepared carbon nanoparticles were found to be 37-89 nm by using powder X-Ray Diffraction technique. DSC/TGA results showed that prepared carbon nanoparticles were stable up to 350 ºC. Surface morphology of carbon nanostructures were studied with the help of scanning electron microscopy. Antibacterial studies showed the average to good results against S. pseudopneumoniae, K. pneumonia, S. aureus and E. coli.
