Re: sorption question

absorption happens when something is taken in and incorporated within
something else - like water in a sponge.

adsorption happens when something forms a thin coat on the outside of
something else - like grease on plastic.

In practice its often hard to tell which process is working so its common
to use the term "sorption" to cover either process.
