The process of electrophilic substitution (ion exchange), occurring under a contact of different samples of bentonite with water-alcohol solution of ammonium chloride NH 4Cl has been studied. The fact of the displacement by the ion [NH 4] + singly and doubly charged cations of s-elements I and II of the D.I. Mendeleev Periodic Table and of significant dependence of the degree of such a displacement in water-alcohol solutions containing ethyl and isopropyl alcohols.
