Based on the data in Problem 11.9, we want to determine the course of adsorption of the mAb if 15 liters of the adsorbent particles are added to 2,000 L of a solution containing initially a 1.0 mg/cm³

concentration of the mAb in a well-mixed tank. The particle radius is 54

μm, and the binding capacity is 110 mg/cm³ of particle volume. Determine the time required to reduce the mAb concentration in solution to 25% of the initial value. What is the lowest possible concentration of the mAb that can be attained for these conditions? For this problem you can assume D_e = 5.0

× 10⁻⁸ cm²/s.
