(a) Breakthrough of deuterated water and bromide versus time expressed as pore volume (water content); (b) modelled breakthrough curves with optimum values for Péclet numbers and the ratio of the anion average linear velocity relative to water, . The dashed lines are for a model including small mixing cells at both ends of the sample, representing the filter discs.
