Growth Kinetics of Silver Bromide Nanoparticles in Aqueous Nonionic Surfactant Solutions

The synthesis of silver bromide nanoparticles has been studied by many researchers because of their wide ranges of applications. This article reports on the growth kinetics of silver bromide nanoparticles in the presence and absence of aqueous nonionic surfactant media. The effects of different parameters such as the reactant concentration, the temperature, and the presence of a nonionic surfactant have also been studied. It was found that these parameters have significant effects on the process of growth kinetics, as well as on the equilibrium particle size. In pure aqueous media, the particle size decreases with increasing reactant concentration. The presence of nonionic surfactant (TX-100) significantly lowers the AgBr particle size compared to that obtained in pure aqueous media.
