Abstract: Silver nanoparticles (AgNPs) were prepared by DC high voltage electrochemical method using a silver anode. The results showed that, for all prepared samples, depending on the size and shape of their nanoparticles, a well-defined UV-Vis peak in aqueous solution induced by the surface Plasmon property of AgNPs was observed at wavelength values in the range of 400-450 nm. Based on the linear dependence betvveen AgNPs concentration and UV-Vis absorbance up to 200 ppm with the R value of 0.9989, the concentration of AgNPs can be derived quantitatively. Thus, this study introduced a simple quantitative method to determine the concentration of silver nanoparticles directly, instead of the total ionic silver that other Chemical, biological or physical methods usually provided.
