TY - JOUR ID - TI - The Properties of Nano-Gold Particles Synthesized by Ascorbic Acid With Acacia Gum and Sodium Hydroxide as Stabilizers AU - Dhelal Abdul Ghafoor1 AU - Rana M. Yas*2 AU - Muna Ahmed Saeed2 PY - 2019 VL - 60 IS - 10 SP - 2149 EP - 2155 JO - Iraqi Journal of Science المجلة العراقية للعلوم SN - 00672904 23121637 AB - In this work, biocompatible gold nanoparticles were synthesized by reducing thechloroauric acid with ascorbic acid as a reducing agent. Colloidal gold nanoparticleswere stabilized through nontoxic acacia gum sodium hydroxide .Synthesizing goldnano particle is confirmed by the change in color of chloroauric acid from yellow toruby red and brown color depending on the stabilizers. The gold nanoparticles werecharacterized by UV-Visible spectrophotometer. Where the peak of the absorbanceof surface plasmon resonance (SPR) was observed between the wave length 526 and535 nm. The results of zeta potential were found in rang (-19, -40 mv), AFM andTEM images show two different shapes, hexagonal and spherical and the size ofgold nanoparticles between 21.5nm and 29nm.
