The Response of Cowpea (Vigna unguiculata L) Plants to Foliar Application of Sodium Selenate and Selenium Nanoparticles (SeNPs)
Author(s): Fatma Abd El Lateef Gharib, Ibrahim Mohamed Zeid, Safia Mohamed Ghazi and Eman Zakaria Ahmed*
The present study describes the synthesis and rapid production of selenium nanoparticles (SeNPs) by reducing selenate in the presence of Ascorbic Acid (AA) as a reductant, coating, and stabilizing agent. The formation of nanosized selenium at 10 mm sodium selenate (Na2SeO4) and 1.5% AA was confirmed by the appearance of the characteristic surface plasmon absorption peak at 296 nm in UV-vis spectra. Transmission Electron Microscopy (TEM) indicates that SeNPs was mostly spherical with a mean diameter of approximately 33.4 nm. X-RAY Diffraction (XRD) pattern confirmed crystalline shape indicating particle size of approximately 42.92 nm. The particle size distribution of SeNPs was approximately 45.9 nm by Dynamic Light Scattering (DLS). Fourier Transform Infrared (FTIR) spectroscopic analys... view more»
