message: The Freunlich equation should be included or linked here. It already has a page, although it is mysteriously unlinked and hard to find; I can't get to it by searching and can't seem to make a link to here work, but it's under chromatography. Perhaps an experienced wikipedian can sort this out.

message: I'm finding that a lot of people--and even some articles on Wikipedia--seem to be confused over absorption vs adsorption, perhaps we should emphasize the difference? I'll add a note concerning the difference. Kr5t 20:17, 12 May 2006 (UTC)

message: The section on Adsorption#Activated_carbon was too long for summary style.  I moved all the content about classifications to activated charcoal.  I think it fits better with activated charcoal anyway. --JeffAMcGee 19:11, 19 January 2007 (UTC)

message: One more thing that should be here on this page is "Adsorption Techniques". So please if someone knows, add them here on the page of Adsorption.

message: I think it'd be good to visualize the isotherms, a la http://kostelec.czu.cz/temelin/conf2004/images/6_izot.jpg
It's easier to compare the isotherms when they're graphed, as opposed to displaying the equations. —The preceding unsigned comment was added by 128.61.120.34 (talk) 20:16, 12 February 2007 (UTC)

message: I think the section on adsorption in viruses should be moved to a sseparate page - it's a physically different process than the fundamental gas-solid processes discussed in this page. —The preceding unsigned comment was added by Dpvwia (talk • contribs) 08:08, 9 March 2007 (UTC)
thread_title:  adsorption in viruses 

message: I would like to edit/delete (parts of) these two sentences (in bold):
1. Adsorption is a process that occurs when a gas or liquid solute accumulates on the surface of a solid or, more rarely, a liquid (adsorbent), forming a molecular or atomic film (the adsorbate).
--Reason: Adsorption to a liquid is not at all rare! The biological world has an abundance of liquid-liquid interfaces (cell-membranes) on which there occur adsorption. Also adsorption to liquids are quite common in chemistry, protein chemistry and nanochemistry.
2. Adsorption is an exothermic process because energy is liberated, therefore enthalpy is always negative.
--Reason: I would just delete that sentence, it's probably correct if you talk about adsorption from a gas, but certainly not from a liquid --> just google endothermic+adsorption, and see for your selfs. Else, it should be stated that it's not a general statement.
agree/disagree?
Comments would be very welcomed,

thread_title:  Some minor corrections I would make 

message: No offence to Mr. Henderson, but the Henderson-Kisliuk adsorption isotherm does not have the same status as e.g. the Langmuir isotherm. Furthermore the section should not read like an abstract from a scientific publication. 
(Reply): Seems like the person writing this sentence has a bit of an issue with Henderson, which speaks to bias and reliability of his/her contribution to this thread.  It is unusual for publishing academics not to be PhD qualified.  If Henderson is indeed a "Mr," not "Dr," the person writing this clearly knows Henderson at a personal level, affecting their objectivity.  If Henderson is a "Dr," the contributor's use of a "Mr" title is clearly intended to slander and belittle Henderson's reputation.  This contributor seems set on reputation destruction and seems to be a risk to the reliability of this thread. - Strongly advise to ignore this person's comments and put up the Henderson-Kisliuk Adsorption Isotherm model.  Would it really be the worst thing in the world to include more material on Wikipedia that could make it even more popular?     — Preceding unsigned comment added by 82.23.140.164 (talk) 17:59, 28 December 2023 (UTC)

message: Question: Does this topic really deserve a whole section here on this page. It seems quite exotic and one can legitimately have doubts on its economical efficiency even if the thermal phenomenon in itself is worth to be explained. I would more focus this section on the phenomenon itself than on its potential industrial application which seems uncertain. It is also based on only one relatively ancient patent (1981), not a proven and well developed technique. It is certainly an interesting phenomenon, but probably with only a marginal development. There is too much emphasis here on the unproven economic development and it can be perceived as self-advertising. Shinkolobwe (talk) 12:38, 13 November 2020 (UTC)
thread_title:  Adsorption solar heating and storage 

message: The current text contains the following:
"Since 1980 two theories were worked on to explain adsorption and obtain equations that work. These two are referred to as the chi hypothesis, the quantum mechanical derivation, and Excess Surface Work, ESW.[15] Both these theories yield the same equation for flat surfaces:"
It mentions two theories, but lists what seem to be three theories, to wit:
# the chi hypothesis
# the quantum mechanical derivation
# and Excess Surface Work, ESW
Now, if one of these phrases would be meant as an apposition to another one, please clarify, e.g. by more proper punctuation. If, on the other hand, the intent is to mention three theories, please replace two by three and both by all three.Redav (talk) 11:27, 14 December 2020 (UTC)

message: The current text contains:
"[...] and "vap" is reference to the vapor pressure of the liquid adsorptive at the same temperature as the solid sample."
Is "adsorptive" used and meant to indicate what is usually referred to as "adsorbate"?Redav (talk) 11:32, 14 December 2020 (UTC)
thread_title:  Adsorptive or adsorbate? 

message: The current text contains:
"Typical standard deviations for full isotherm fits including porous samples are typically less than 2%."
Me not being an expert in the field, I am wondering whether one of "Typical" and "typically" may safely be removed.Redav (talk) 11:38, 14 December 2020 (UTC)
replies: text: What you are describing is a basic edit for readability, if you feel your English is good enough, then you don't need to be a subject matter expert. I'll take out "typically". Wikiwayman (talk) 08:51, 31 December 2020 (UTC)
