Exact solutions of the problem of adsorption-desorption dynamics with a nonlinear sorption isotherm

Analytic solutions of the problem of adsorption-desorption dynamics with a nonlinear Sorption isotherm are obtained for cases of practical importance in which the Danckwerts condition is satisfied at the inlet to the porous medium and the adsorbate concentration in the mobile phase at the surface of the porous medium is given.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 5, pp. 107–112, September–October, 1989.
