Fig. 2. Breakthrough curves of Cl^-, brilliant sulfaflavine (BF), and sulforhodamine B (SB) in different soil core (# refers to soil core number) layers. Normalized concentrations, c = C/C₀, in the outflow from soil cores are plotted vs. cumulative drainage. C is the concentration in the effluent; C₀ is the input concentration. Lines are breakthrough curves predicted by the convection dispersion model that is calibrated to the Cl^- breakthrough.
