Abstract

An approach has been proposed for determining the space-time parameters of the formation process of Liesegang rings. This approach relates the processes of the formation of nanoparticles and dense periodic precipitates from them. Dynamic light scattering is employed to reveal periodic variations in the intensity of light scattered by nanoparticles with different sizes, from which Liesegang rings are formed. A relationship between the periods of the variations in the intensity of light scattered by nanoparticles (microscopic process) and the times of the formation of Liesegang rings as a whole (macroscopic process) has been found.
