Green Synthesis of Nano-Size Silver Particles Colloidal Sol

Abstract:

Article Preview

Using starch as the stabilizing agent, glucose as reducing agent, nano-size silver particles colloidal sols have been synthesized via ultrasonic irritation in aqueous solution. The synthesis process is completely green and the colloidal sols are safe to environment and human, and can be used as antibacterial agent in biology, medicine, food packaging and hauseware fields. The synthesis technology parameters for the silver particles with diameter of 15 to 45 nm, such as the ultrasonic power, reaction time, reaction temperature, concentrations of silver nitrate and capping agent were determined and discussed. The typical colloidal was characterized by ultraviolet-visible spectroscopy (UV-Vis), transmission electron microscope (TEM), X-ray powder diffractometer (XRD) and Zeta Sizer Nano Series.
