It is desired to study the removal of a contaminant A dissolved in water by adsorption on a porous solid. To do this, a spherical porous adsorbent of radius R is put in contact with an "infinite" volume of contaminated water. Adsorption can resemble a first order reaction. The maximum concentration of the contaminant that the adsorbent can accept is C Af There is a resistance to mass transfer between the contaminated water and the solid, given by a mass transfer coefficient k. Formulate the model whose solution would provide the concentration profile and clearly explain the initial and boundary conditions.
