Abstract  

The kinetics of Na+–UO 22+ and Mg2+–UO 22+ ion exchange on strongly acidic cation exchangers in a batch stirred reactor has been studied. The exchangers Ostion KS (containing DVB in the range of 1.5–12%) and Amberlite IR 120 for experimental work were used; the concentration of the aqueous nitrate solution was always 0.2 mol·l–1. The Nernst-Planck equation was applied for description of ion diffusion in the particle. The diffusion coefficients of UO 22+ ions in the exchangers and their dependence on the content of DVB were obtained by evaluating the experimental data.
