Maybe it should be called differently, because it's a physical rather than chemical process. Also categorization is probably bad, but I was trying to be consistent with adsorption. Hope somebody more knowledgeable in physical chemistry will fix this. Samohyl Jan 00:36, 11 Jan 2005 (UTC)

• • This process is more associated with chemical engineering than chemistry. It is widely used in industry to scrub exit gasses.

I deleted the link to the Physics Category page as part of the effort to clean up said page. StuTheSheep 03:04, Mar 23, 2005 (UTC)

Yes, it is a chemistry topic but in modern physical chemistry

This is written in jargon, not English, and needs to be rewritten if it is to be any use. Ewjw 08:58, 27 November 2005 (UTC)[reply]

Midget impingers and fritted bubblers are common sampling equipment used by an Industrial Hygienist in evaluating airborne contaminants that can be absorbed in a liquid media.

The expansion request from January 2005 (not from me) asks:

Absorption (chemistry) should be at least as long as adsorption, and it should contain similar information about equilibriums in solutions (and the relevant formulas or links there), and so on.

I am going to remove the IUPAC definition for the following reasons:

1. If the definition were quoted exactly from the source, that would likely be a
   copyright violation
   .
2. The definition as provided appears to be a paraphrase of the original, but this introduces elements of
   original research
   to assert that the paraphrasing is equivalent to the original.
3. Wikipedia is not a dictionary
   .

The reddish color of copper is an example of this process because it is caused due to its absorption of blue light.'

Doesn't belong here, isn't absorption in the sense of this article. Andres (talk) 08:13, 13 February 2016 (UTC)[reply]

"Moisture regain" redirects to this article even though it wasn't defined, or even mentioned, anywhere in the article and I can't find it in the history. It is related to absorption, so I've made a quick addition to the article. If you feel it doesn't belong here, please find somewhere better to put it, oh and update the redirect if needed. :) Thanks.

The article was flawed but i improved it. original talked about Nernst whatever law which must be well known or else would not be used casually in an explanation of a process? - wrong: Wikpedia has no article of the mentioned Nernst whatever, however it seems to have a whole bunch of pages that mention somewhere some other Nernst whatevers. After some detective work that should not have been necessiated if the article was properly written to begin with it seems that Nernst was dealing with solutions, eg soultion of one substance in another, equilibrium of solutions when two different solvents compete for the same soluable material, etc. So it seems that the thing mentioned has to do something with the ratio of solvent and soluable and the rate of the solving process, etc. Probably this article would have been better off if Nerd was left out and instead it would have talked about the better efficiency of chemically solving something than phisically mixing the same thing. Nevertheless Nerds rules and equilibriums and whatevers are mentioned in many other articles, so probably Nerd deserves a mention on a side note as an mportant contributor to the science but that belongs to history of science rather than the description of the process of solving/absorption, etc.

Besides: while the distinction between ABsorption and ADsorption is important as it clarifies a really long ongoing and quite disurbing misunderstanding - it should be also noted that the distinction between absorption and adsorption in an example of a liquid absorbent is rather trivial since a liquid cant have (?) OK, maybe just usually doesnt have a distinct bulk and a distinct (inner) surface - in contrast with solid structures like active charcoral. Maybe even better were to point out that normally adsorption means a solid material with lots of cracks or bubbles inside creating a large surface that the filtered material can stick to, while liquids dont have such a surface and instead can filter out the same substance by bulk, hence the different term absorption for the latter process.
