Recent investigations of natural zeolites as adsorbents in water and wastewater treatment, their properties and possiblemodification of natural zeolites have been a subject of many studies. Various natural zeolites around the world have shown good ion-exchange capacities for cations, such as ammonium and heavy metal ions.

Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that rapidly heating the material, believed to have been stilbite, produced large amounts of steam from water that had been adsorbed by the material.

* A "-" sign preceding a three-letter code indicates that the framework is interrupted. That is, not all T atoms are 4-connected.
The Atlas of Zeolite Structure Types [4], published and frequently updated by the IZA Structure Commission, assigns a three - letter code to be used for a known framework topology irrespective of composition. Illustrative codes are LTA for Linde zeolite A, FAU for molecular sieves with a faujasite topology (e.g., zeolites
