Abstract160Tb was used as radiotracer and the equilibria and kinetics of $$3\overline {Na} + Tb^{3 + } \rightleftarrows \overline {Tb} + 3Na^ + $$ cation exchange with zeolite-Y were studied. The ion exchange isothems and the Kielland plots at 298 and 303 K were obtained. It was found that the ion exchange rate is controlled by particle diffusion. The integral interdiffusion coefficients for the direct and reverse exchanges at 298 K and 303 K were calculated. In addition, the $$\overline… CONTINUE READING
