Fig. 7. Obtained D_eff–values in either the whole cell, the source (desorption) half-cell or in the recipient (adsorption) half-cell for (a) Hiroshima (t = 1200 h, except for t_{short equilibrium} = 840 h, (b) Yolo (t = 816 h), (c) Lerbjerg 5 (t = 672 h) and (d) Lundgaard (t = 456 h, except for t_{short incubation} = 384 h), shown as a function of water content. Also shown is the D_eff values estimated from the batch adsorption (broken line) or desorption (solid line) using Freundlich isotherm parameters (Table 4) and the best-fit longer-term linear isotherm (K_D) (dotted line).
