Right, the distinction is fine here.

Adsorption is due to weak bonds that form between molecules of a surface and a fluid. AFAIK this bond is not a 'new' chemical bond since it does not break / replace existing chemical bonds in both the adsorbed molecule and surface molecules.

Rather, in the case of carbon at least, the 'bonds' are the van der Waals forces.
