ABSTRACT

Natural and waste water clearing of cations of non-ferrous and heavy metals is an important problem of modern industry. Metals inflow into natural water occurs in various ways from natural leaching from rocks via industrial processing stage to natural water bodies and watercourses discharge. The most large-scale and significant way of non-ferrous and heavy metals’ cations hitting represents waste water of technological processes of metallurgical and mining and processing industry. The obtained results show that ferromanganese nodules are promising natural materials with high capacity, developed surface and sorption selectivity in relation to non-ferrous metals.
Thermodynamic characteristics extreme sorption meanings, seeming constant of ion-exchange sorption Gibbs energy were found during experiments. Lyotropic series based on received data were made up on surface of FMN, which was compared with analogous series shown in literature. The obtained data let us to value radius of sorbed cations. We made a conclusion about their partial dehydration.

Keywords: ion-exchange sorption, ferromanganese nodules, radiuses of sorbed cations, Gibbs energy, lyotropic series cations.
