Fig. 1. Flow rates for various leaching experiments for (a) Column A and (b) Column B. (•) -100 mm Br step-up, continuous; ({circ}) -20 mm Br step-down, continuous; ({blacksquare}) -20 mm Cl step-up, continuous; ({square}) -20 mm Cl step-down, intermittent; ({blacktriangleup}) -20 mm Br step-up, intermittent. The term I is drainage.

Fig. 2. Measured and predicted (using convection–dispersion equation, CDE) concentrations of (a) bromide and (b) chloride for (•) Column A and ({circ}) Column B as a function of drainage, I (mm). Both solutions were applied continuously.
