Adsorption Database Initiative Launched

The most recent International Adsorption Society email newsletter announced the launch of an initiative to create a database for pure component gas and vapor adsorption isotherms in porous solids. The announcement, which can also be found on the International Adsorption Society’s website, is reproduced below, with kind permission of Professor Talu. We would like to strongly encourage both our customers and other readers of this blog to support this interesting and important initiative. So, please submit your published data now!

Announcement of adsorption database on International Adsorption Society website


Dear Colleague,

We have undertaken a major effort to create a database for pure component gas/vapor adsorption isotherms in porous solids. The database will be published by Springer in electronic format in fall 2013. It will be easily accessible/searchable/downloadable. We hope that it will be a very useful tool for all scientists and engineers working in the adsorption area.

As we go through thousands of articles in journals, I am afraid that we might miss some data. Hence this Email to provide you with the opportunity to ensure that all your contributions are included in this central database.

Furthermore note that this is a great opportunity to be recognized for your data published only in graphical form in the past. If you respond to this Email, we will be happy to include your data in tabular form to make it more useful to other researchers for process simulations, multicomponent equilibrium predictions, kinetic analysis, etc. (with a citation to the original article).

In case you are concerned about copyright issues, the lawyers assure me that individual data included in a publication does not carry copyright privileges. There is no concern for you to contribute, or us to compile, data from copyright protected publications.

Specific instructions below describe what and how to send us information about your published work. Please feel free to forward this Email to other individuals who might be interested.

I thank you in advance for your effort in helping us to compile the only inclusive isotherm database in literature.

P.S. I apologize for multiple copies of this Email which may reach you.




Email for all communications:


Data to be included:

*) pure component gas/vapor equilibrium data (isotherm, isobar, isostere)

*) only porous solid as adsorbents

*) only previously published data (in tabular and/or graphical form)

*) only EXCESS adsorption data (by Gibbs dividing surface definition)


Please send:

1)      Reference for the original publication

2)      Data table(s) as Email attachments

a.      Data points as rows, properties as columns (pressure, temperature, amount adsorbed)

b.      Specify property columns and units for each column (preferred units kPa, K, mole/kg or milimole/gm)

c.      Preferably data sorted in the order collected to identify adsorption/desorption points

d.      Repeat the property held constant at each row (e.g. temperature for isotherms)

e.      If more than one isotherm is included in the table, add another (4th) column to identify each isotherm

3)      If the same solid is used in different publications, please provide cross-references (so that the solid will appear only once in the database)


Electronic format for Email attachments:

1)      Preferably in Microsoft Excel format, or

2)      Any text (ASCII) format delimited/separated with a character, or

3)      Any file format recognizable by Excel (please indicate software)
