Abstract. Kinetics of the reaction of silver nitrate reduction by hydrazine in the presence of sodium citrate in alkaline medium was studied in a wide range of the reagents concentration variation. The orders of the reaction were determined and the effective constants of the silver nanoparticles nucleation process rate and of their propagation one were calculated. It was investigated the optical characteristics of the obtained sols of the silver nanoparticles. It was determined the empirical dependence of a size of the obtained silver nanoparticles on the kinetic parameters of a process.
Key words: silver nanoparticles, nucleation, nanoparticles growth, kinetics, hydrazine.
