Abstract
The effect exerted by surface modification of natural aluminosilicates, glauconite and clinoptilolite, with ferrocyanides on the parameters of selective 137Cs sorption was studied. The modification leads to an increase in the specific sorption and in the radiocesium interception potential in the presence of potassium, RIP(K). RIP(K) of the modified sorbents NPF-Gl and NPF-Cl was 6.1 × 105 and 5.0 × 106 mmol kg–1, and the specific sorption capacity, 138 ± 14 and 136 ± 12 mg g–1, respectively. The regular trends in variation of the 137Cs distribution coefficients in sorption onto the natural and modified sorbents at K+ and Са2+ concentrations ranging from 10–4 to 2.0 M were found. The modified sorbents exhibit high specificity to 137Cs in a wide range of Ca and K concentrations in the solutions.
