Fig. 18.20 Comparison of normalized uptake of 1,4-dichlorobenzene (DCB) to Pahokee peat
(PP) soil (a-d) and to Beulah-Zap lignite (BZL)(e-h) during sorption kinetics of bulk (SKB) and
forward isotope exchange at the sorption point (FIES) or during desorption kinetics of bulk
(DKB) and reverse isotope exchange at the sorption point (RIES) at low and high concentrations
indicated on the graphs. M is the cumulative mass of DCB taken up or released, and M
f
is the final
mass taken up or released by the geosorbent. C
Eq
is the final leveling-off concentration, and CTO
is the initial concentration before initiation of DKB and RIES, left lower concentration; right
higher concentration filled symbol, bulk; open symbol tracer. Reprinted from Sander and
