    Abstract

    A series of chalk samples from the cretaceous formation overlying the Erslev salt dome have been studied in order to establish permeabilities, porosities, dispersion-, diffusion-, and sorption characteristics of the chalk, Predominantely the investigations have been carried out by application of a liquid chromatographic technique. The chalk was found to be porous (ε ≅ 0.4), however, of rather low permeability (k = 10-7 cm/sec).  It was found that the material exhibits a retarding effect on the migration of cationic species as Cs+, Sr2+, Co2+, and Eu3+, whereas anionic species as Cl- and TcO-4 move with the water front.
