Аннотация:The kinetic dependences characterizing the influence of equilibrium factors on the diffusion processes in selective ion exchangers and in the solution film around the bead have been compared. A formal similarity of these dependences is shown to eliminate the possibility of identifying the kinetic mechanism in selective systems using conventional methods for non-selective exchange. The relationship between mass-transfer rates in the ion exchanger AV-17 and in the solution film has been analyzed for the desorption of Ag(S2O3)3- 2, selectively retained by the exchanger, using sodium chloride solutions. The results of the analysis confirm the above conclusions.
