Abstract
AbstractSilver 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 between 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.
