Green synthesis of silver nanoparticle using seaweed as the stabilizer by sonochemical irradiation method
Silver nanoparticles (Ag-NPs) were successfully synthesized from AgNO3 through a green method under sonochemical irradiation and using eco-friendly stabilizer which was seaweed Kappaphycus alvarezii (K. alvarezii). The formations of Ag/K. alvarezii were clarified by the surface plasmon resonance (SP...

| Summary: | Silver nanoparticles (Ag-NPs) were successfully synthesized from AgNO3 through a green method under sonochemical irradiation and using eco-friendly stabilizer which was seaweed Kappaphycus alvarezii (K. alvarezii). The formations of Ag/K. alvarezii were clarified by the surface plasmon resonance (SPR) under UV-visible spectroscopy which had absorption peak around 384-387 nm. Zeta potential results determined the stability of Ag-NPs after 720 min irradiation. The FTIR spectrum indicated the presence of K. alvarezii in capping with Ag-NPs; in addition, EDX spectra and SEM images shown the spherical shape of the Ag-NPs. |
