[en] Sorption capacity of some natural, technogeneous, and industrial materials (carbonic and mineral) and also of composite sorbents based on them with respect to radionuclide mixtures has been determined. These materials are promising for decontamination of natural and industrial waters wastewaters and for the removal of corresponding nonradioactive impurities from these waters

[en] Sorption ability of some natural, technogenic and technical materials (carbonic and mineral ones), as well as, of composition sorbents on their base as to the mixture of radionuclides was determined. Perspective character of the composition sorbents for decontamination of natural, technical effluents and for purification of those objects from the respective non-radioactive impurities is shown. 9 refs.; 5 tabs

[en] Sorbing capability of microamounts of ruthenium, rhodium and palladium depending on chemical nature of the surface of carbon materials on the basis of natural coals, solution composition, medium acidity, other factors, has been defined. A high selectivity of certain materials as regards ions of the above metals, potentiality of their extraction in the presence of 500-1000 -fold excess of ignoble metals (copper, chromium, iron, cobalt, nickel) has been ascertained and its reasons have been discussed. 13 refs.; 2 figs.; 2 tabs
