| Abstract: | Equilibrium, kinetics, and dynamics of rhenium desorption from weakly basic macroporous (Purolite A170) and gel anion (Purolite A172) exchangers with ammonia solutions were studied. The effective diffusion coefficients of rhenium in its desorption from these anion exchangers and the activation energy of rhenium desorption from the gel anion exchanger were estimated. |
