ABSTRACT
Little is known about the adsorptive capacity of activated
carbon in removing chlorinated phenols. particularly when
they are present in mexture. The present work detenni ned
the adsorption capacity for pentachlorophenol, 2, 4, 6­
trichlorophenol, 2, 4-dichlorophenol, 2-chlorophenol and
phenol as a function of chlorine sUbstitution.
Results have showed that the more highly substituted
with chlorine the phenol molecule is. the better the
adsorption of the undissociated molecule.
In multi solute systems. competitive adsorption resulted
In mutual inhibition of the adsorption capacity of each
solute. However. the total adsorption capacity of carbon
at equilibrium was higher for multisolute systems.
