A new solution to the kinetics of a fixed-bed adsorber in response to a step change in feed concentration is obtained for a linear equilibrium system, considering the resistance to mass transfer in both the mobile and stationary phases. The differential equations of continuity and mass transfer are integrated by simulating the intraparticle concentration profile with a parabola. The results agree with Rosen's rigorous but complex solution.
