A Zeolite bed is the core of an oxygen concentrator. The pressure swing adsorption process uses zeolite as a molecular sieve. Room air is compressed into a zeolite bed, then the remaining air components are drawn off. The bed is then released to atmosphere, the zeolite releases the nitrogen, and the process is restarted. By removing the nitrogen from regular air, you get a mixture of mostly oxygen with traces of carbon dioxide and Argon.

Unless someone can put some citations into that mess of a paragraph about QuikClot to clear up whether it's calcium silicate (which the New Scientist article seems to refute, given that it mentions an alternative to QuikClot being made of calcium and silica) or a zeolite (which the New Scientist article doens't explicitly state), the whole thing should be deleted or remarked out of existence until it can properly cited. dil 18:59, 5 April 2007 (UTC)

An advance has reportedly been made in "trapping" CO2 molecules in ZIFs, or zeolitic imidazolate frameworks. I'm unsure if it should be covered here as I'm not too well introduced in the subject, but I'm posting the link FYI and also did in the external links section: http://www.scienceblog.com/cms/material-selectively-swallows-co2-15480.html What I'm wondering is if it should have an extra mention in the "Uses" section, or if this is somehow too unrelated for that. — Northgrove 01:03, 15 February 2008 (UTC)
ZIFs are not zeolites. They are a subclass of metal-organic materials that have imidazolate as organic linker and a zeolite-like topology. —Preceding unsigned comment added by 128.40.197.43 ( talk) 12:37, 26 February 2008 (UTC)
2nd sentence: "The term was originally coined in the 18th century by a Swedish mineralogist named Axel Fredrik Cronstedt who observed, upon rapidly heating a natural mineral, that the stones began to dance about as the water evaporated." "...the water..."? What water, Fire-water? It's good someone cares enough about etymology to try- but this purported explanation explains little to me; I cant even understand it well enough to correct it- nor should I, because as an article opening it serves as a warning, to question or review the subsequent techinical writing.

The picture labeled "zeolite" needs a more descriptive caption. There are (as of writing) 179 different zeolite frameworks, and the mineral shown could be any one of the 48 or so different naturally-occurring zeolites. Kaiserkarl13 ( talk) 18:55, 4 November 2008 (UTC)
The emphasis of this article is heavily skewed towards mineralogy. Synthetic zeolites are important as industrial catalysts, and there is little mention of their preparation, properties, uses, or unique structures.
This article states that there are 80 naturally occurring zeolite frameworks, but the citation provided does not list 80 unique zeolites. For example, Chabazite-K and Chabazite-Ca are NOT unique frameworks; they're both CHA. Similarly, faujasite-Ca and faujasite-Na are the same structure (FAU) with different counter-ions (they're also the same as NaY, HY, NaX, CsX, and a bunch of other synthetic zeolites that have different ions and/or compositions but the same framework connectivity). The number this refers to should reflect the number of frameworks (of the 179 currently discovered) that occur naturally, NOT the number of names we've come up with to describe different compositions of the same material.

Even though some sites give zein as the lemma of the root of the word, that is actually the infinitive form [1]—the usual lexical form for ancient Greek is the indicative form, which is zeō [2] (cf. wiktionary:ζέω). 24.243.3.27 ( talk) 17:09, 26 February 2009 (UTC)
Wikipedia should reflect reality, the real life. In real life, zeolites are widely used as nutritional supplements. (As of now, Google search 'zeolite supplements' returns 470,000 hits.) So this should be reflected in Wikipedia somehow. Yet, up to now, this was not reflected in Wikipedia in any way. Do we see a problem here? -- Dyuku ( talk) 18:11, 5 December 2009 (UTC)
"The silicalite sol formed by the hydrothermal method is very stable. Also the ease of scaling up this process makes it a favorite route for zeolite synthesis."
the word hydrothermal is linke to the Hydrothermal circulation page, which talks about a geologic process, which is not amenable to the manufacture of synthetics. —Preceding unsigned comment added by 71.117.211.16 ( talk) 03:19, 3 July 2010 (UTC)
Nowhere does it say that zeolites have negatively charged frameworks, it is implicit in the only chemical formula quoted. The charged framework is why ion exchange happens and why zeolite acids cane be formed. There are neutral molecular sieves such as aluminophosphates. Axiosaurus ( talk) 10:03, 7 February 2013 (UTC)

The article tells us that detergent manufacture is the largest use of zeolites, but then fails to tell us anything else. If this is the largest use, I'm sure it deserves more than a single sentence. At the very least, the article could tell us whether the zeolites are used as a catalyst in the manufacture, as a reactant, or one of the ingredients of the product.

Several editors tried to include paragraphs on medical use of zeolite or paragraphs on zeolite as nutricional supplement. These paragraphs have always been removed by other editors with an explanation, that medical articles have not been published in peer reviewed journals, or that this is a fringe science, or that there are no proofs of relationship between zeolite and cancer treatment. Yesterday an article published in one of the leading journals was added to the article and it was soon removed. It is also a fact that many people, especially in Eastern Europe, believe that zeolites cure cancer. Probably they are wrong. However, the fact that there is such a great interest in this issue, this issue deserves at least a short paragraph in wikipedia. Those searching or googling for zeolite are mostly interested in its medical use (see google search suggestions) and they deserve to get at least one short paragraph. Another issue is, what should be included. It is undisputed that there are medical articles in highest ranked journals on this subject. It is also undisputed that these articles come mostly from the same authors from Croatia. It is also undisputed that this is what could be called fringe science, because mainstream science does not follow their view. It is also undisputed that some companies, mostly in Central and Eastern Europe (Austria, Slovenia, Croatia, Serbia), promote zeolite as a cancer cure. It is also undisputed that many people search for answers on wikipedia on this subject (see google search suggestions: zeolite benefits, zeolite side effects, zeolite cancer, zeolite wikipedia). Therefore I suggest that a short paragraph on this subject should be included. It should not promote zeolite. It is acceptable to note that zeolite medical use is promoted by fringe science and that its benefits are not proven. Maybe an article should read something like this: A group of Croatian researchers has published an article on natural zeolite clinoptilote effects on cancer treatment (Pavelić, K., Hadžija, M., Bedrica, L., Pavelić, J., Ðikić, I., Katić, M., ... & Čolić, M. (2001). Natural zeolite clinoptilolite: new adjuvant in anticancer therapy. Journal of Molecular Medicine, 78(12), 708-720.). Several other articles have been published by same authors. No other authors or studies have confirmed or denied the relationship between zeolite and cancer. Croatian company Panaceo (www.panaceo.hr) promotes zeolite as a cancer- treating and other deseases- treating cure in Croatia, Serbia, Slovenia, Austria, Bosnia, and some other neighbouring countries (panaceo.si, panaceo.at). The relationship between authors of the article and the zeolite sellers is unknown, but they are both from Croatia. 31.15.180.165 ( talk) 08:56, 5 May 2015 (UTC)

If stuff is captured by a zeolite filter, is that it? Are there ways to (easily) get it back out? Like, for example, you trap a short lived radioactive substance in zeolite but after a couple of years it has decayed and you'd really want to get the decay product out because it is valuable. Would such a thing be possible? If so, how? Hobbitschuster ( talk) 01:12, 17 January 2022 (UTC)
