摘要：

Extralattice aluminum species were extracted from hydrothermally dealuminated Y zeolites. The 0.1 M HCl was applied for this purpose. Under given working conditions, treated samples retained their crystallinity, checked by i.r. and adsorption measurements. I.r. spectra in the hydroxyl stretching region gave important information about the origin and nature of different types of OH groups observed.
