MONTMORILLONITE INTERCALATED BY COMBINED OLIGOMERIC FE-NI COMPLEXES

The properties of montmorillonite intercalated by the combined oligome ric Fe-Ni complexes has been studied by XPA, IRS, DTA, and benzene ads orption methods. It has been proved that the interlayer space of the m odified montmorillonite is 16.2-16. 7 angstrom and does not change app reciably with increase of the hydroxo-complex content. The modificatio n causes make the specific surface of the initial clay mineral to grow from 65 to 207 m2/g. The porous structure of the modified montmorillo nite is stable until the temperature reaches 800-degrees-C.
