Talk:Activated carbon

Carbon!
- Old encyclopedias mention "bone black" on this topic...maybe that phrase should appear somewhere...
- User:Polyparadigm
- It appears that bone black is slightly different than the processed activated carbon.
- Why do we have that second link on the page? It appears to have nothing to do with carbon, other than that the students applying for the internship/grant money might use it...

Incomprehensible
"Tests of adsorption behaviour are usually done with nitrogen gas at 77 K under high vacuum, but in everyday terms activated carbon is perfectly capable of producing the equivalent, by adsorption from its environment, liquid water from steam at 100 °C and a pressure of 1/10,000 of an atmosphere." Seems unintelligible to me. Does it mean that adsorption tests are done with both nitrogen gas and activated carbon? If so, what is the role of liquid water in such a prosedure, and the meaning of pressure? Should the quoted content be simplified, explained, divided to multiple parts or what? 193.166.173.23 13:55, 1 Jun 2005 (UTC)
Ok, I think I got it. Adsorpion can be tested either with gas or steam. They way it's told is really tricky tho. 193.166.173.23 16:53, 1 Jun 2005 (UTC)
