The adsorption of a ca 5.4 x 10(-5) M aqueous solution of methylene bl
ue has been examined on five activated carbon samples. The equilibrium
concentrations (C-e) were determined by spectrophotometry studies. Th
e analysis of Freundlich adsorption isotherms obtained provides the ad
sorption capacity of each carbon sample. (C) 1997 Elsevier Science Ltd
