The kinetics of adsorption of ammonium ions under
dynamic conditions has been studied. A mathematical model of
the process was built. The mass transfer coefficient was
calculated depending on the intensity of the change of location.
It was established that ion exchange occurs in external and
internal diffusion regions. The rate constants of ion exchange
for the region of external and internal diffusion were calculated.
