Study of ion exchange at test solutions purification from nickel (II) ions with gabbro-diabase from abzakovo deposit

The paper presents the results of the study of ion exchange processes during the purification of model solutions from nickel ions with gabbro-diabase from the Abzakovo field. The features of the minerals structure that make up gabbro-diabase predetermine their sorption and cation-exchange properties. During the studies, the course of sorption processes was established, as well as the presence of a suspension effect in the system. By determining the concentration of exchangeable cations (Ca²⁺, Mg²⁺, Al³⁺) in the crystal lattices of gabbro diabase and Ni^{2 +} cations contained in the model solution, the phenomenon of cation exchange purification has been proved. The treatment of gabbro diabase powder with electromagnetic radiation increases the mobility of exchange cations and water treatment efficiency. (paper)
