The paper describes the different works realized in our laboratory on a pulsed bed reactor containing a granular electrode used to the synthesis of conducting polymers. It presents results on different points: the hydrodynamic behaviour of the reactor and the influence of the hydrodynamic conditions on transfer phenomena in the process; the kinetic characterization of the reactions; the relation between the process and the polymer properties and the influence of the operating conditions on the evolution of these properties. In addition to the study of these different phenomena, we propose a simulation of the reactor permitting to predict the evolution of the monomer concentration in the solution and of the polymeric film thickness. Finally, the particles coated by the polymeric pellicular phases have been used for the recovery of metallic ions in solutions.
