"Webfrom the time before adsorption became understood in the 1920's. A better term is “activated carbon.” Carbon is activated by the pyrolysis of coal, wood, bark, coconut husks, etc. to remove all the volatile material as a gas or vapor, and leave only the carbon. This carbon might then also be partially oxidized to enlarge its pores. " - How does carbon adsorption work
