Zeolite - Wikipedia
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.
Ammonium removal from wastewaters using natural New ...
The potential use of zeolites for removal of NH4+ from New Zealand agricultural wastewaters was recognised by Cooke et al. (1992). If natural New Zealand zeolites have a strong capacity to remove NH4+ from pond discharges, they may be used at the end of a two-pond system or within an oxidation pond-constructed wetland sequence as a filtering bed.

Zeolite - an overview | ScienceDirect Topics
Zeolites are highly crystalline aluminosilicate microporous insoluble materials with a rigid three-dimensional open framework that may be of natural or synthetic origin. Their high stability facilitates considerable freedom of ion exchange and many other applications such as in catalysis and in gas adsorption/storage, including NO [11, 33, 67] .
