Abstract

Precipitate forming chemical reactions have been studied in chemically crosslinked poly(vinyl alcohol) gel medium. One of the reactive components was incorporated into the gel, the other was allowed to diffuse into the swollen network. This reaction‐diffusion process often results in pattern formation which can occur intermittently in terms of time and space or both. Experiments were carried out in order to investigate the effect of various factors (crosslinking density, swelling degree as well as the concentrations of the outer and inner electrolyte). The following precipitates were intensively studied: Mg(OH)2, Cr(OH)3, PbCl2. Three basically different morphologies (Liesegang band formation, moving bands and tree‐like structure) have been observed and investigated. One‐ and twodimensional computer simulations were carried out in order to establish the influence of various factors on the precipitation.
