Abstract
Regarding widespread applications of sulfur and capability of nanoscale particles, we are reporting the synthesis of green sulfur nanoparticles (GSNPs) through precipitation reaction of aqueous sodium thiosulfate catalyzed by oxalic acid assisted in presence of an organic and herbal surfactant. The herbal surfactant-Saponin- was extracted from a native plant called Acanthe Phyllum Bracteatum known as ÇoÄŸan in Urmia West Azerbaijan, Iran. The GSNPs were characterized by Dynamic Light Scattering (DLS), Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), Atomic Force Microscopy (AFM), Energy-dispersive X-ray Spectroscopy (EDX) and Fourier Transform Infrared Spectroscopy (FT-IR). Based on the obtained data, the size of GSNPs was recorded between 30 to 50 nm. The truly fine sulfur nanoparticles owe their nanoscale size to micelle formation around the sulfur particles supported by saponin aggregation.
