The removal of Radium isotopes from water can be achieved by passive filters with high efficiency and at low costs. The filters are made of a novel granulated sorbent of high sorption capacity and selectivity. This contribution describes the development, results of laboratory investigations and the practical use of the sorbent Hedulat based on Barium Sulphate embedded into foamed inorganic Geopolymer. Apart from its suitability for the selective removal of Radium from contaminated waters (e. g., from seepage and mine effluents of Uranium mining) it is also well-suited to the treatment of mineral and drinking waters under certain circumstances.
