On the kinetics of ion-exchange adsorption in a fluidized ion-exchange bed
Abstract
Ion exchange is widely used in hydrometallurgy, especially in the extraction of rare earth or ferrous elements from solutions. The field of application of ion exchangers in non-ferrous metallurgy can be significantly expanded, firstly, if sufficiently cheap and high-capacity domestic ion exchangers are available, and secondly, if the mechanism of the ion exchange process is known, which makes it possible to obtain, analyze and use appropriate kinetic equations. For a number of cations (copper, zinc, etc.), the domestic cation exchanger KU-2 can be confidently attributed to the number of ion exchangers meeting the first requirement. Not having selectivity with respect to ions of a certain type in the combined presence of several ions, the KU-2 cation exchanger turns out to be quite high-capacity with respect to each of the cations individually.
