چکیده انگلیسی

A simple and environmentally friendly method was developed for preparing colloidal silver nanoparticles in aqueous solutions using silver nitrate, sodium alginate and glucose as silver precursor, capping agents and reducing agents, respectively. The formation of silver nanoparticles was observed by the change of color from colorless to yellow. The silver nanoparticles were characterized by transmission electron microscopy (TEM), UV-visible spectroscopy (UV-vis) and X-ray diffraction (XRD). The TEM images show that the particles are small, well dispersed and spherical in shape with a narrow distribution from 3 nm to 12 nm. The XRD demonstrates that the obtained metallic nanoparticles are single crystalline silver nanoparticles. The effects of the reaction time, the reaction temperature and the concentration of silver ion and reducing agent on the particle size were investigated by the UV-vis spectra. The present process is an excellent candidate for the preparation of silver nanoparticles because it is simple, free-pollutant, inexpensive and easy to perform. The method may be extended to other noble metals, such as Au, Pd and Pt, for medicinal, industrial and technological applications.
