چکیده

This paper reports the effect of temperature, presence of impurity (Fe3+), and crystal seed on the induction time of silver nanoparticles. In this study, Ag precipitation was achieved by solution reduction and the experimental induction time was measured by monitoring the absorption of the solution after creation of supersaturation. Experimental induction time was compared to the cluster coagulation models (the Smoluchowski model and its’ variation cluster coagulation model) and the conclusion is that the conventional Smoluchowski coagulation model works better than the modified version.
