Introduction
In the current literature on the determination of sorption parameter values, all
authors use mathematical descriptions related either to kinetics or statics of this
process (treated as separate processes) (Seidel-Morgenstern
2004
; Chiang
2005
).
Thus, the literature lacks any attempts at determining relationships between the
linear and nonlinear sorption kinetics rate constants (
k
1
;
k
2
) and the parameters of
the adopted linear or nonlinear sorption isotherms
resulting from static
equilibrium-controlled models. Such connections between kinetics and statics
make it possible in practice to eliminate the dynamic complex experimental
research with mobile groundwater (carried out on laboratory models

and the very long-lasting and expensive field research in natural ground media by
using considerably simpler and shorter static laboratory research with an immobile
contaminant and groundwater.
In dynamic research of a sorption process for contaminant and groundwater
movement through the ground, the determination of linear and nonlinear sorption
kinetics rate constants (
k
1
;
k
2
) requires that the so-called breakthrough curves BTCs
(named also transition curves through analyzed lengths of ground media) be defined
every time (Letcher
2004
; Bekhit and Hassan
2007
). One has to remember,
however, that the constant parameters of linear or nonlinear sorption isotherms
(
K
1
;
N
) can be defined in a simple static laboratory research with immobile
groundwater (Seidel-Morgenstern
2004
; Aniszewski
2009
).
