The adsorption of 4-chlorophenol on an expanded commercial clay used in water purification has been studied. Experiments using 4-chlorophenol concentrations of 50, 100, 250, 500, 750, 1000, 1250 and 1500 mg L-1 were carried out in column reactors at 25ºC.A new adsorption kinetics equation has been developed based on the equation for the variation in solute concentration in the liquid phase, representing the difference between the adsorption rate minus the desorption rate that at equilibrium represents the Langmuir isotherm. This was used to derive a new finite equation for the development of the adsorption curve.
