Abstract
Physicochemical features of the sorption of Sr, Cs, and U radionuclides on natural mineral sorbents (montmorillonites of Na and Ca type, kaolinites, illites) were studied. The main processes responsible for binding and retention of radionuclides are ion exchange and formation of complexes on the mineral surface. The influence of pH, salt composition of the solution, specific surface area of the sorbent, and its pore size on the radionuclide immobilization efficiency was examined. [ABSTRACT FROM AUTHOR]
