Sorption properties of industrial sorbents, from solutions of the Paratunsky, Pauzhetsky and Malkinskoye deposits of the Kamchatka Territory were studied. The parameters of ion exchange on cation exchangers (TOKEM-160, AMBERLITE IR-120) under static conditions are determined. Sorption isotherms are constructed and quantitative characteristics are determined. A comparative analysis of the dependence of lithium ion extraction on the type of sorbent is presented. Selective series of cation extraction for ion-exchange resins have been constructed, which are an important indicator in the extraction of lithium from aqueous solutions with a very low content in comparison with other alkali and alkaline-earth metals.
