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.

“…2 Currently, one of the most common strategies for the remediation of pertechnetate focuses on the use of sorption methods using the anion itself or perrhenate as a less hazardous surrogate. Recent studies employ bentonites, 3 carbazole derivatives, 4 cationic electrospun fibers, 5 modified commercial resins, 6,7 layered double hydroxides, 8 cationic polymeric networks, 9−11 mineral incorporation, 12 and coordination polymers (CPs). 13−16 Among these options, CPs are promising for adsorption applications because they are versatile materials that can be tailored in terms of structural features that are fundamental for successful ion exchange, namely framework charge, topology, and pore size.…”

Pertechnetate, the most stable form of the radionuclide 99Tc in aerobic aqueous systems, is a hazardous anion present in nuclear waste. Its high mobility in water makes the remediation of the anion challenging. In the past decade, significant effort has been placed into finding materials capable of adsorbing this species. Here, we present the synthesis and high-resolution crystal structure of the coordination polymer [Ag(2,4′-bipyridine)]NO3, which is capable of sequestering perrhenatea pertechnetate surrogatethrough anion exchange to form another new coordination polymer, [Ag(2,4′-bipyridine)]ReO4. Both the beginning and end structures were solved by single-crystal X-ray diffraction and the adsorption reaction was monitored through inductively coupled plasma-optical emission spectroscopy and UV–vis spectroscopy. The exchange reaction follows a pseudo-second-order mechanism and the maximum adsorption capacity is 764 mg ReO4/g [Ag(2,4′-bipyridine)]NO3, one of the highest recorded for a coordination polymer or metal–organic framework. A solvent-mediated recrystallization mechanism was determined by monitoring the ion-exchange reaction by scanning electron microscopy–energy-dispersive spectroscopy and powder X-ray diffraction.

“…Among them, anion exchange is considered to be a feasible strategy because of its low cost and relatively simple operation. Hence, many cationic materials were designed and constructed for the elimination of target anions, such as anion-exchange resins, , cationic polymeric networks, , layered double hydroxides (LDHs), , covalent organic frameworks, and metal–organic frameworks (MOFs). , MOFs are crystalline porous materials synthesized by organic linkers and metal ions/clusters . Benefiting from tunable topology structure, high specific surface areas, easy synthesis, and regular pore structure, many MOFs were designed for capturing pollutants. , Among various materials with ion-exchange ability, cationic MOF constructed by neutral organic ligands and metal ions can utilize weakly coordinated or free anions to capture harmful anions through anion-exchange .…”

Sequestration of toxic oxo-anions (such as 99 TcO 4 − and ClO 4 − ) from wastewater has received constant attention due to the existing serious threat to public health and the sustainability of the environment. In view of the low energy of hydration of TcO 4 − and ClO 4 − , cationic metal−organic framework (MOF) materials with the hydrophobic microenvironment are preferred in the selection of sorbents. Herein, a twofold interpenetrated cationic MOF (ZJU-X15) with double-helical chains was constructed by tetrakis[4-(pyridin-4-yl)phenyl]ethene (TPPE) and Cd 2+ for the elimination of 99 TcO 4 − and ClO 4 − . Profiting from hydrophobic channels, ZJU-X15 could remove most of ReO 4 − (a surrogate for 99 TcO 4 − ) and ClO 4 − in less than 10 and 20 min, respectively. As the result of batch experiments, ZJU-X15 could capture 356 mg of ReO 4− and 221 mg of ClO 4 − per 1 g of sorbent, showcase decent selectivity, and still maintain high removal efficiency for anions after four recycles. Furthermore, the process of anion-exchange was confirmed by ion chromatography, Fourier-transform infrared spectroscopy, scanning electron microscopy combined with an energy-dispersive X-ray spectrometer, and X-ray photoelectron spectroscopy, indicating that target anions successfully entered into the body of ZJU-X15 through anion exchange.
