Biosynthesis of Silver Nanoparticles Using Peel Extract of Raphanus sativus L.

Fadel QJ and Al-Mashhedy LAM

In present study, Silver nanoparticles (AgNPs) were synthesized using peel Raphanus sativus L extract that acts as a reducing and stabilizing agent. The AgNPs formation was observed as a color change of the mixture from red to dark-brownish we have developed a green synthetic method for silver nanoparticles using peel of R. sativus extract. Silver Nanoparticle prepared were characterized by using UV–visible spectroscopy, Scanning electron microscopy(SEM), X-ray diffraction (XRD) and Dynamic light scattering (DLS). The best Condition of experiments includes temperature 50°C, pH 9, time 0.5 h, sliver nitrate concentration 1 mM and mixing ratio of the reactant on sliver nanoparticles synthesis 5:95. The AgNPs showed surface plasmon resonance at 430 nm, size ranges from 34 nm to 50 nm determined by using a laser particle size analyzer (DLS).
