英文摘要	Groundwater is an important source of freshwater in Egypt. With growing populations and human activities in Egypt, the demand for groundwater has increased. In this study, sodalite was successively synthesized from low-cost natural clay materials (kaoline) and white sand using the fusion with the NaOH method. The conditions of hydrothermal crystallization (zeolitization) were found at a temperature of 170 degrees C, and a time span of 72 h for raw material. Sodalite has been characterized by X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, and differential thermal analysis/thermogravimetric analysis. Sodalite was tested as adsorbents for reducing a variety of salinity total dissolved solids with Na cation from groundwater of Wadi El-Assiuti, Egypt. Batch experiments were carried out to investigate the effects of some parameters (dosage of adsorbent, pH, temperature, and contact time) on both salinity and the Na+ ion adsorption. The results showed that sodalite has a good efficiency in the removal of salinity and the Na+ ion with concentrations up to 6,000 and 1,320 ppm respectively. The percent adsorption was evaluated with changes in the previous parameters for different concentrations of Na1+ ion. The Langmuir constants model for Na1+ ion sorption on the adsorption isotherms is fitted well. The R-L value in the present investigation at concentration 1,320 ppm was less than one, indicating that the adsorption of the metal ion by sodalite is favorable. Freundlich adsorption isotherm is also adapted in the case of sodalite (R-2 = 0.7) for Na+ ion.
