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.

“…Targets were placed in a cassette located in the irradiation chamber. Before conducting measurements, a vacuum was created in the chamber with a pressure of 10 -4 Pa. To excite characteristic X-ray radiation (XRR) of Cs, Sr, and Co atoms, a proton beam with a current of 200 nA and an energy of 1400 keV was used [12,14,15]. At this energy, the characteristic X-ray radiation of the L-series of cesium atoms and the K-series of strontium and cobalt is effectively excited.…”

“…XRR exited the chamber through a 25 μm thick beryllium foil window. In previous studies to determine the content of cesium, strontium, and cobalt ions, for the optimization of spectrometric conditions for XRR spectra formation, a collimator with hole diameters of Ø 1.5 mm and polyethylene absorbing films 150 μm thick were used [12,14,15]. X-ray spectra were processed using the WinQXAS code.…”

Two methods of using permanent NdFeB magnets and their impact on the sorption of radionuclides (Cs, Sr, Co) by clinoptilolite and composite sorbents based on zeolites are discussed. Sorption processes were considered under dynamic conditions with liquid circulation. No changes in sorption processes were observed when magnetic treatment was applied to solutions containing radionuclide ions. The natural zeolite clinoptilolite and synthetic zeolites NaX and NaA were considered at this stage. In the work, clinoptilolite from the Sokirnitske deposit in the Zakarpattia region of Ukraine was used. Ukraine possesses significant deposits of clinoptilolite. When magnets were applied to the sorbent during the sorption process, an increase in cobalt sorption of 10% was observed for clinoptilolite, and strontium sorption increased by 17%. The influence of a magnet on clinoptilolite is due to the presence of iron ions in the composition of clinoptilolite. The iron content ranges from 0.9% to 2.5%. The composition of the composite sorbent included clinoptilolite and synthetic zeolite NaX. No increase in radionuclide sorption was observed for composite sorbents, likely due to the presence of clinoptilolite in the sorbent composition and the corresponding iron content. The analytical part of the study was carried out using the PIXE (Particle Induced X-ray Emission) method on the analytical nuclear-physics complex "Sokil." The energy range of the accelerator was 200-2000 keV. The complex made it possible to carry out all the main methods of analysis using ion beams. The targets were placed in the exit, at the Chamber for PIXE. To excite the atoms of cesium, strontium, and cobalt a proton beam with an energy of Ер≈1400 keV was used.
