摘要

The framework aluminum content of normal and dealuminated zeolite-Y may be obtained from Si(29) n.m.r. data, unit cell constants or positions of infrared bands due to T-O stretching modes. Using n.m.r. data as the primary means for determining framework aluminium the following equations were obtained: N sub Al = 107.1(a sub O - 24.238); N sub Al = 0.766(1086.7 - nu sub 1); N sub Al = 1.007(838.8 - nu sub 2); where N sub Al is the numbers of aluminium ions per unit cell, a sub 0 is the unit cell constant in Angstrom, nu sub 1 is the wavenumber for the asymmetric O-T-O mode and nu sub 2 is the wavenumber for the symmetric mode.
