Abstract
The sorption behavior of natural aluminosilicates (bentonite and clino ptilolite) and aluminosilicates modified by ferrocyanides of heavy met als has been studied relative to radionuclides Cs-137 and Sr-90 in the presence of various quantities of alkali and alkaline-earth ions. It has been shown that the distribution coefficients of the modified samp les may exceed 100 for Sr2+ and 10,000 for Cs+; however, with a concen tration of mineral background over 1.0 g . liter-1, the competing ions strongly depress the sorption properties of the aluminosilicates.
