Résumé :
|
The practical aspects of pollutant migration by diffusion through clayey barriers is presented. The discussion is generally restricted to soils of ph=8 which contain carbonate. A short review of the theoretical aspects of the nature of diffusion is incorporated with description of methods for measuring or calculating diffusion coefficients. The importance of retardation and the use of distribution coefficients is emphasized.
