Abstract—Basic characteristics of sorption (distribution coefficient and sorption capacity) were analyzed in
pure minerals and mineral mixtures sampled from weathering mantle over ultramafic rocks. The investigated
material can be recommended as a specific sorbent for radioactive Cs- and Sr-containing substances buried
underground and for waste water purification.
