Studying the mole ratio effect of Na2O /SiO2/Al2O3 on 4oA zeolite synthesis and investigating of its structure by XRD

Zeolites, especially zeolite A, have been widely employed as builders in several regions of the world and emerged as the preferred phosphate substitute for powder detergents. The aim of this study is to investigate the proper process parameters of synthesizing 4oA zeolite by hydrogel process (the mole ratio effect of Na2O /SiO2/Al2O3) and to characterize the synthesized material by means of XRD analysis, Ca exchange capacity, SEM, IR and atomic absorption spectroscopy.
