Abstract
Silver nanoparticles (Ag-NPs) were successfully synthesis from AgNO3 through a green method under sonochemical irradiation by using seaweed Kappaphycus alvarezii (K. alvarezii) as biopolymer media. Many methods for synthesis Ag-NPs reported such as chemical and physical techniques however many of them have environmental risk. This paper aims to study the green synthesis Ag-NPs using seaweed K. alvarezii due to an eco-friendly stabilizer and sonochemical irradiation method. The formations of Ag-NPs/K. alvarezii were determined by the surface plasmon resonance (SPR) under UV-visible spectroscopy that was observed at 377-387 nm. Zeta potential results indicated that these nanoparticles have good stability after 720 min irradiation. SEM-EDX analysis confirmed the element of Ag and spherical shape of the Ag-NPs. The FT-IR spectrum described the presence of K. alvarezii and Ag-NPs
