Effect of ultrasonic radiation’s times to the control size of silver nanoparticles in κ-carrageenan

Effect of ultrasonic radiation’s times to the control size of silver nanoparticles in... The sonochemical method as a green method for the preparation and size control of silver nanoparticles (Ag-NPs) formed in κ-carrageenan has been developed. κ-carrageenan was chosen because it is an eco-friendly stabilizer and ultrasonic irradiation reducing agent. Formations of Ag/κ-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 κ-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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals
