Abstract: The iron content Fe(s) in Fe-Y type zeolites lattice was determined by combining lattice constant determination by means of XRD with chemical analysis of the ratio of Si/Al In spite of the existence of iron impurity the contribution of iron in skeleton to the lattice constant can be distinguished and the experimental data showed a linear relation between mole fraction of iron in lattice and lattice constant. As a result of this study an empirical equation was obtained:(Fe(s))/(Fe(s)+Al+Si)=((Si/Al)×(α_0-2.4070)+(α_0-2.5476))/(0.5560×Si/Al+0.3884)
