Abstract
In this article the thermodynamic characteristics of the process of ion exchange sorption of non-ferrous metals in ferromanganese nodules (FMN) are presented. Ion exchange is described by an equation similar to Langmuir isotherm. The values of the apparent limiting sorption and ion exchange constant are also counted.
Keywords: ferromanganese nodules, Gibbs energy of the ion exchange, ion-exchange sorption, Langmuir isotherm, lyotropic number of cations, radii of sorbed cations
