Sorption properties of strontium and barium on kaolinte, montmorillonite, chlorite + illite type of mixed clay and soil fractions have been studied by using batch technique at room temperature. 90Sr and 133Ba were used as tracers. Montmorillonite type clay was found to sorb strontium more strongly than the other clays whereas chlorite 4-illite mixed clay was found to be the best sorbent for barium. Variation of distribution ratio, Rd, as a function of cation concentrations exhibited characteristic inverse S-shaped curves. Sorption isoterms were well described by Freundlich and Dubinin-Radushkevich equations in all cases.Hatipoglu Sinan, Eylem Cahit, Göktürk Hale, Erten Hasan N.
