Abstract
Adsorption of radon in the artificially enriched water was investigated on magnetite, Fe3O4, and charcoal activated powder (activated carbon). Linear models of Langmuir, Freundlich and Dubinin-Radushkevich isotherms showed that radon adsorption on both adsorbents is a favourable chemical process, with weaker interactions with magnetite, that takes place forming a multilayer of adsorbed radon. The efficiency of both adsorbents was at a similar level but, because of the larger density and magnetic properties, magnetite could be more suitable in practical applications when smaller volume of adsorbent is advisable.
