Surface-Modification of Sulfur Nanoparticles with Surfactants and Application in Agriculture

This work presents the results of obtaining the sulfur nanoparticles, which can be used in agriculture as a fungicide. Sulfur nanoparticles were obtained by modifying the surface of sulfur using various surfactants including cetyltriammoniumbromide (CTAB), sodium dodecylbenzene sulfanate (SDBS) and Triton X-100 (TX-100). The size, crystal structure and morphology of sulfur nanoparticles were determined by methods as laser size analyzing (LSA), X-ray diffraction (XRD), scanning electron microscope (SEM). It was found that the nanoparticles had a sulfur monoclinic β-form struture, and their average size was in the range of 1000-1500 nm.
