Abstract

The silver nanoparticles are synthesized by the green method using Salix semi-solid extract. Fresh leaves are prepared in a semi-solid extract form that retains active substances and can be preserved for a long time. The parameters of the synthesis process are optimized by examining the effects of pH, Salix semi-solid extract concentrations of extract and AgNO3 concentrations through the UV-Vis absorption spectrum of synthetic particulate solutions. The composition of atoms and surface functional groups are determined through EDX measurement and FTIR infrared absorption spectrum of Salix semi-solid extract and synthetic silver nanoparticles. Silver nanoparticles are used to study the biodegradability of organic coloring Rhodamine B (RB). The results showed that silver nanoparticles synthesized by this green method provided an optical degradation efficiency of up to 88.5%. This work shows that silver nanoparticles synthesized from Salix semi-solid extract can be used in the decomposition of dye waste that contributes to the cleansing of the water environment.
