Synopsis

A mass transport model has been developed to predict theoretical breakthrough curves in fixed bed adsorbers. The model has been tested using experimental data obtained for the adsorption of Acid Blue 25 on chitin. The effective diffusivity can be determined for the adsorption process by best fitting experimental and theoretical breakthrough curves and was found to be 5.5 X cm2 s-'.

THEORY

Spahn and Schlunder5 used a method which assumed an irreversible isotherm, i.e., the solute concentration in the solid is independent of the *To whom correspondence should be addressed.
