Sonochemical method for the synthesis of silver nanoparticles in κ-carrageenan from silver salt at different concentrations
A green sonochemical method was developed for preparing silver nanoparticles (Ag-NPs) in j-carrageenan in different concentrations of AgNO3. The j-carrageenan was used as an eco-friendly stabilizer and ultrasonic irradiation as a green reducing agent. The number of Ag-NPs increased with increasing c...

| description | A green sonochemical method was developed for preparing silver nanoparticles (Ag-NPs) in j-carrageenan in different concentrations of AgNO3. The j-carrageenan was used as an eco-friendly stabilizer and ultrasonic irradiation as a green reducing agent. The number of Ag-NPs increased with increasing concentrations of AgNO3. Formation of Ag/j-carrageenan was determined by UV–visible spectroscopy where the surface plasmon absorption maximum was observed at 410–416 nm. XRD analysis showed the Ag-NPs are of a face-centered cubic structure. TEM images showed the well-dispersed Ag-NPs with an average particle size \5 nm. SEM images showed the spherical shape of the Ag-NPs. The FT-IR spectrum indicated the presence of j-carrageenan in capping the Ag-NPs. The use of photo irradiation provides a green and economic method features to the synthesis reported in this study. |
