Abstract

Static and dynamic Liesegang structures have been studied experimentally and by means of computer simulation. Reaction diffusion differential equations of the system were solved by method of finite differences. Equations were based on Ostwald’s supersaturation theory and a modified sol coagulation model. It was possible to reproduce the normal as well as the revert type of Liesegang phenomenon. In the case of dynamic structures effect of the initial concentrations and structure of the polymer matrix have been studied.
