Abstract:
Five nickel (II) A - Zeolites (16.6-76.6% exchanged) were investigated using volumetric, gravimetric, spectroscopic and magnetic susceptibility techniques. Upto 65% exchanged the following vacuum dehdration sequence was determined: Ni2+-(H2O)6 (Octahedral) 340K Ni2+ +-(H2O)3 (Ox)3 (Trigonal) bipyramid) 620K Ni2+(Ox)3 (Trigonal) (Where +(Ox) represents the oxygen atom of the lattice of the zeolite). All the zeolites except 77% exchanged, showed the retension of the aluminositcate framework structures both after preparation and upto 620K evacuation.
