The average gain of the free, bound, and total solute mass uptake at time

as
a function of
k

. For
k
1
≤
1 the graphs for free and total solute coincides because the concentration
of bounded solute is orders of magnitude less than free solute concentration
.
On Figure 6 the average gain of free, bound, and total solute mass uptake by the

k

. For
k

gel at time

the gain approaches its

=
k

≥
value for not binding solute, and the graphs for free and total solute coincide because
the concentration of the bounded solute is orders of magnitude less than the free solute
concentration.
Figure 7 shows the gain of free, bound, and total solute mass uptake by the gel
as a function of time for
R
g
1000
and
k

=

. When compared with Figure 3, where
=
the same graphs for
R
g
100
are plotted, the large increase in gain for bigger
R
g
can
be seen. To generalize this result, Figure 8 shows the effect of
R
g
on the average gain
of free, bound, and total solute mass uptake by the gel at time

0.2 (for

). Note that
k

depends on
R
g
, but it was set at constant value in this
plot because the effect of
k

can be neglected compared with the
effect of
