From: Insights into transport velocity of colloid-associated plutonium relative to tritium in porous media
Breakthrough curves for Pu and tritium in the porous media under the conditions of 0.002 mol/L Na+ and different water flow rates (Q).
The dash lines indicate the effluent volumes where the collection percentages (Cp) of Pu (black) and tritium (red) are overall equal to 50%. The difference in their effluent volumes (blue line areas), i.e. VS= VT(Cp = 50%) − VPu(Cp = 50%), is the separation volumes (Vs). The initial trace-level concentrations of Pu (C0) ≈ 10−9 mol/L. The error bars resulted from the standard deviations of C0 (three samples) and from the measured relative standard deviations (RSD) of C.
