“…On the other hand, K + and NO 3 are released in the leachates from both tuffs, Be 2+ and Pb + (from Beli Plast) and F − (from Golobradovo.) So far, zeolites have only been considered as possible sorbents of fluorides from fluoride-rich waters (purification) [12,13,70,71], but not as a possible source. Our study shows that F − can be exchanged/desorbed from the tuffs into the aqueous media.…”

“…There is an established methodology for water treatment in treatment plants to obtain safe drinking water depending on the original water source [8,9]. Despite the established methods for the purification of drinking waters, in some cases, modified natural and synthetic zeolites are used for the removal of heavy metals (Cu, Cd, Pb, and As), fluorine, and NH 4 + [10][11][12][13]. Since ancient times, zeolites were used for drinking water purification [14].…”

The migration of 32 elements from natural zeolitized tuffs from the Beli Plast and Golobradovo deposits (Bulgaria) was determined in ultrapure, tap, mineral, and coal mine waters in order to evaluate their desorption and adsorption properties. The tuffs are Ca-K-Na and contain clinoptilolite (90 and 78wt.%, respectively), plagioclase, sanidine, opal-CT, mica, quartz, montmorillonite, goethite, calcite, ankerite, apatite, and monazite. The desorption properties are best revealed during the treatment of ultrapure, tap, and mineral water, whereas the adsorption properties are best manifested in coal mine water treatment. The concentrations of Al, Si, Fe, Na, Mn, F, K, Pb, and U increase in the treated ultrapure, tap, and mineral water, while the content of K, Be, Pb, and F increase in the treated mine water. The tuffs show selective partial or complete adsorption of Na, Mg, Sr, Li, Be, Mn, Fe, Co, Ni, Cu, Zn, Al, Pb, U, and SO42−. They demonstrate the ability to neutralize acidic and alkaline pH. Sources of F are presumed to be clinoptilolite and montmorillonite. The usage of zeolitized tuffs for at-home drinking water treatment has to be performed with caution due to the migration of potentially toxic and toxic elements.

Natural Zeolites are crystalline aluminosilicates with very particular properties, both physical and chemical, such as reversible water adsorption, ion exchange without modifications in their structure, and the adsorption of molecules, acting as a molecular sieve. In the present work, a review of the main applications of Natural Zeolites (ZNs) has been carried out. Essential topics have previously been introduced to understand the nature of ZNs, from their discovery, origin, and main properties; the primary deposits worldwide are also mentioned. The importance of these materials has been increasing over time due to the wide variety of applications implemented, thanks to the creativity and ingenuity of researchers. From ion exchange (II) and adsorption applied to the removal from water of heavy metals, ammonium ion, arsenic, fluorine, etc., to applications in Agriculture (fertilizers, animal nutrition, soil amendment), (the development of agribusiness generates substantial amounts of wastewater). In Medicine (disinfection for Escherichia coli, mycotoxins, bacteria, and antiviral, among others), in Catalysis, Space Project, etc. The above justifies the name that Mumpton gave to the ZNs: “The magic rock.” This review shows some summarized examples and provides other references on each topic. Innovative applications continue to be obtained in the literature, and this “mini-review” is hoped to be helpful.
