Abstract

The sonochemical method as a green method for the preparation and size control of silver nanoparticles (Ag-NPs) formed in ?-carrageenan has been developed. ?-carrageenan was chosen because it is an eco-friendly stabilizer and ultrasonic irradiation reducing agent. Formations of Ag/?-carrageenan were determined by electronic spectroscopy where the surface plasmon absorption maxima were observed at 437-412 nm. The FT-IR spectrum indicated the presence of ?-carrageenan in capping with Ag-NPs. The XRD analysis proved that the Ag-NPs were of a face-centered cubic structure. TEM images displayed well-dispersed Ag-NPs with an average particle size of less than 10 nm. SEM images indicated the spherical shape of the Ag-NPs.
