“…The chemical analysis of the adsorbent (Table 1) shows that (SiO 2 + Al 2 O 3 ) represents 80 wt.% of the mineral. The SiO 2 /Al 2 O 3 ratio is 4.02; this value controls the formation of zeolites, which is close to the lower limit for mordenite given by the literature at 4.15–5.15 (Hernáandez et al , 2000; Khoury et al , 2015). Biotite, hematite and feldspar are accessory minerals and affect the colour of the tuff (Bouzidi et al , 2014) because these minerals contain transition metals such as Fe 2+ , Ti 3+ or Mn 2+ .…”

This work examines a tuff from the Tinebdar deposit located in Sidi Aich (east Algeria) for possible use as an alternative material for the adsorption of Asucryl red (a textile dye). Natural tuff represents an economic and environmentally friendly alternative compared to synthetic zeolites. The starting materials were characterized by means of powder X-ray diffraction, Brunauer–Emmett–Teller-specific surface area and pore diameter analysis. Batch experiments were performed and various parameters that have an effect on the adsorption process (i.e. pH, clay amount, contact time and initial concentration) were investigated. The <125 μm grain-size fraction of the tuff contains 45 wt.% mordenite. The adsorption equilibrium was established in 10 min and the adsorption kinetics were better described by the second-order kinetic model. The adsorption isotherm of the results obtained fits better to the Langmuir and Timkin models. The adsorption capacity qt varies from 60 to 70 mg g–1 with temperature increasing from 293 to 333 K. The thermodynamic nature of the adsorption process was determined by calculating ΔH°, ΔS° and ΔG° values. The positive value for ΔH° confirms that the adsorption is endothermic.

The proposed genetic models of zeolite deposits include weathering, diagenesis in open or closed hydrological systems, low-temperature hydrothermal systems, primary magmatic environments, and impact craters. Most of the occurrences of zeolite occur in one of the following geological environments: saline or alkaline lakes, alkaline soils, diagenetic, open system, hydrothermal and marine sediments, or by the alteration of volcanic glass, as mentioned by Costafreda 2014;Luz, 1995;Clifton, 1987;Sheppard, 1975.…”

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.

“…Therefore, it might be envisaged their use in a number of favorable geological context where zeolitite should be largely available. We can consider for instance: oceanic volcanic islands (like Hawaiian and Canary islands [45]), specially "old" mature volcanic islands where chemically evolved magmas erupt in form of large-sized pyroclastic rocks [47]; pristine arcisland environments or thin immature continental crustal segments (like large segments in the Panamá-Guatemala region in Centro America); in pyroclastic sectors of the large intraplate ood basalt regions [48] or other within plate large basaltic outcrops [49,50]; and of course in the only case of emerged mid-ocean ridge, Iceland (where widespread hydrothermal metamorphism in zeolite facies is well exposed in the marginal, older, eroded sectors of the island [51]). Thus, we can conclude that there is not availability a reason for the margination of phillipsite-chabazite zeolitites from industrial uses.…”

Ionic exchange tests have been performed on superficial wastewaters to remove ammonia by the use of a volcanic zeolitized rock from Lazio Region (Central Italy). The zeolitite (natural zeolite) is characterized by chabazite, phillipsite and minor amounts of sanidine, leucite and analcime. After preliminary column experiments in laboratory focused to determine the saturation time of the zeolitite, a pilot plant was built up on a little water course near the area of San Giustino channel (Abruzzo Region, Central Italy). Wastewaters, characterised by starting ammonia value ranging between 5 and 120 mg/l, were filtered with a zeolitic bed. The first experimental results indicate a positive ammonia reduction of about 80-90% and, in all cases, NH4+ concentration values under the EU law limits. A main purpose of this paper is to evidence that most of studies published on uptake of ammonia by means of zeolitite lead with clinoptilolite-dominant zeolitite despite the large availability and best performance of phillipsite-chabazite zeolites. Last but not least, a large number of published studies are of difficult comparison because of poor characterization of the zeolitite used.
