Abstract
- A green sonochemical method was developed for preparing silver nanoparticles (Ag-NPs) in κ-carrageenan in different concentrations of AgNO. The κ-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 AgNO. Formation of Ag/κ-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 κ-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. [ABSTRACT FROM AUTHOR]
