A mathematical model of the lithium adsorption process in a packed column, taking into account the saturation of the sorbent with the absorbed component, is presented. The Langmuir model is used to estimate the equilibrium in the system. A granular material based on the compound (LADH-Cl) is considered as a sorbent. The calculations of the sorption column are based on finite differences in time and coordinate. The results of calculations of lithium release in the packed adsorber for various process conditions are given, showing the efficiency of the adsorption extraction method. The conclusion is made about the prospects of practical application of the lithium adsorption process for certain ranges of its concentrations in solutions.
