Preparation and study of the structural and optical properties of silver nanoparticles prepared from extracts of some plants

Abstract

The study included the preparation of silver nanoparticals using Punica granatum extract . as silver nanoparticals were prepared by biological method . which is one of the best ways for its cheapness and the fact that is does not require time and does not leave toxic substance .in the study , the active compounds of the extract were detected and some physical properties of AgNps were studied . the optical and structural properties of the prepared nanoparticles were studied by Uv-Visible spectrophoto meter measurement. perform an infrared spectrophotometric test (FTIR ) a filed – emitting scanning electron microscope was also performed , ( EDX ) , ( X-RAY ) and the results of ( FESEM ) measurement showed that silver nanoparticles are of oval shape , and of different sizes ranging from ( 32.55 -70.55 ) nm . with a rate of (45.98) nm .
