Abstract

The aim of this study is to synthesize and characterize gold nanoparticles. For this purpose, the reduction reaction between tetrachloroauric acid and sodium citrate was used. At the end of the reduction reaction, gold nanoparticles with narrow size distribution were obtained. The initial gold concentration, trisodium citrate concentration and mixing rate were changed and their effects on particle size and size distribution were investigated. The optimal gold salt concentration, trisodium citrate concentration and mixing rate were found 0.06 mM, 0.17 mM and 450 rpm, respectively. Zeta sizer has been used to characterize and determine the size and size distribution of the synthesized gold nanoparticles.
