Breakthrough curves for Pu, tritium and Sr²⁺ in one porous media system under the conditions of water flow rate Q = 2.27 mL/min, water content θ = 0.306 cm³/cm³, Sr²⁺(C₀) = 0.0065 mol/L and Na⁺ = 0.01 mol/L.

The dash lines indicate the effluent volumes where the collection percentages of Pu (black), tritium (red) and Sr²⁺ (blue) are overall equal to 50%. The tailing data (behind a point) resulted from desorption of Sr²⁺ were not considered as the contribution to the collection percentage of Sr²⁺. The differences in their effluent volumes (green line areas) are the separation volumes between both Pu/tritium and tritium/Sr²⁺. The error bars resulted from the standard deviations of C₀ (three samples) and from the measured RSDs of C.
