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.

“…Reaksiyonlarda büyük bir yüzey alanı sağlarlar. Zeolitler katyon/iyon değiş tokuşu sağlarlar, moleküler seçicilik ve adsorbsiyon/desorbsiyon özelliği gösterirler, su yumuşatıcılardır, mükemmel katalizörlerdir ve ayrıca biyolojik olarak aktiflerdir [9]. Bu üstün özellikler zeolitlerin çok çeşitli uygulama alanlarında kullanımını mümkün kılmaktadır.…”

Zeolitler, volkanik aktiviteler sonucu yeryüzünde doğal olarak oluşan ve sentetik olarak da yüzlerce çeşitte üretilebilen zengin element içerikli alüminasilikat mineralleridir. Zeolitler ayırt edilebilir homojen poroz yapıya sahip, yüksek yüzey alanlı iyonik bileşiklerdir. Bu kimyasal ve mikroyapısal özellikler zeolitlere yüksek adsorpsiyon ve absorpsiyon kapasitesi, iyon-değişimi, moleküler seçicilik gibi etkinlikler sağlar. Bu çok yönlü üstün özellikler de zeolitlerin tarım ve hayvancılık sektörlerinden, enerji, teknoloji ve biyomedikal sektörlerine kadar çok geniş bir yelpazede etkin olarak araştırılıp kullanılmasının önünü açmıştır. Bu çalışmada zeolitlerin temel özellikleri, uygulama alanları ve spesifik olarak biyomedikal ve doku mühendisliğinde zeolitlerin önemi, güncel, potansiyel uygulama alanları araştırılarak öz bir şekilde ele alınmıştır.

“…The arrangement has a tetrahedral structure as the main building unit, with each oxygen atom shared with another tetrahedron [5,6]. In addition, zeolite is a framework composed of cavities and channels with size dimensions varying between 3 Å and 30 Å, in which the channel size determines the physical and chemical properties and some applications of this material [7].…”

“…The three main components of a zeolite are an alumina-silicate framework, exchangeable cations, and water content [7]. The amount of water content in the zeolite framework varies due to the crystallization conditions and the cations exchanges through the cavities and channels.…”

Effect of NaOH Concentration Toward the Characteristics of Activated Natural Zeolite from Blitar – East Java

This study discusses the activation of natural zeolite from Blitar City – East Java using NaOH solution (0.5 M and 1.0 M). Characteristics of unactivated and activated zeolites were also investigated, as well as the effect of the activator (NaOH solution) on functional groups, element composition, pore size, specific surface area, and total pore volume. FTIR spectroscopy, XRF, and gas physisorption were conducted to support the study. Experimental data showed that: (1) the major functional groups were observed at 1250-780 cm-1 in the infrared spectra, in which the unactivated and the activated zeolite were not significantly different; (2) the elemental composition of zeolite (Si and Al) tended to decrease after the activation process; (3) the pore size of the activated zeolite increased while the surface area and total pore volume decreased. Based on this study, activated zeolite (AZB-1.0) showed the optimum result: the pore size increased by 4.12847 nm, and the total pore volume did not decrease significantly by 0.04987 cc/g.
