摘要：

The external porosity of a gel-type resin bed was evaluated from the mean residence time of a non-adsorbing solute. In order to select a tracer that does not penetrate inside the resin, the resin porosity available to the solute was evaluated by fitting breakthrough curves with a model accounting for diffusion in particles and axial dispersion in a column. Examples are given of the applicability of the method.
