The method of quantitative determinaltion of "hydroxyl nests" by DTA and TGA was established. The concentration of "hydroxyl nests" for NH4Y and NaY zeolites dealuminated with an aqueous oxalic acid solution was determined by snch method. The results indicated that the "hydroxyl nests" concentration of the dealuninated zeolite sample is compatible with its number of actual dealumination per gram. This shows that after a framework aluminum of zeolite was removed by acid, a "hydroxyl nests" formed conclusively.
