SIMULATION OF ION EXCHANGE INTERACTION KINETICS IN THE CLINOPTYLOLITE - AMMONIUM ION SYSTEM

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.
