摘要

Means for the separation of radium from water, in particular by means of natural uranium and its natural decomposition products, radioactively contaminated waters by means of a reactive material consisting of several components, characterized in that a homogeneous mixture of a mineral structural material with a large inner surface and finely divided barium sulfate in the form of a geopolymer - barium sulfate - granulate from geopolymer - powder with a mass fraction of 5% to 25%, curing agent, with a mass fraction of up to 15%, water with a mass fraction of up to 10%, barium sulfate with a mass fraction of 50% to 85% and hydrogen peroxide with a mass fraction of up to 5% is made, wherein first of all the components geopolymer - powder, curing agent and water are mixed, barium sulfate, and hydrogen peroxide metered in, and then again be mixed, and then the homogeneous mixture for the curing in the flat containers and, after the hardening is crushed and classified.
