Abstract : The kinetics and mechanism of the formation of silver nanoparticles (AgNPs) by reduction with ribose and glucose were studied spectrophotometrically under pseudo-first-order condition in aqueous micellar media over 45 – 60 oC and variety of [OH-] range. The rate of reaction increases with increasing of the [OH-]. Cetyltrimethylammoniuom bromide (CTAB), sodium dodecyl sulphate (SDS) were used as stabilizer for the formed silver nanoparticles. The Effect of [Ag+], [sugar], [NaOH] and [micelles] on the reaction rate was investigated. The proposed mechanism is derived which is consistent with the experimental rate law. Thermodynamic activation parameters were calculated. The particle size of silver sols was characterized by the transmission electron microscopic (TEM), SEM and physio-chemical and spectroscopic methods.
