【 摘 要 】

Research of the study on the effect of para-hydroxybenzoic acid as a reducing agent on the stability, size, and shape of silver nanoparticles has been done. In this study, pH variations were carried out to examine the effect on silver nanoparticles growth. Besides, various concentrations of AgNO3 precursors were also performed to see the effect on the number of silver nanoparticles formed. Nanoparticles tested for their stability, shape, and size using UV/Vis spectrophotometer. The Transmission Electron Microscope (TEM) was used to characterize the shape and size of the formed silver nanoparticles. The results showed that the conditions of silver nanoparticles formation was at pH 9 with uniform morphology and the diameter of 34 ? 1.78 nm. Furthermore, from the less decreasing and small shift of the 6 weeks of age silver nanoparticles UV spectrum, it has been proven that the nanoparticles have good stability.
