WebJun 17, 2024 · Adams–Bohart model. Adams–Bohart model (Bohart and Adams 1920) was obtained using mass balance in the adsorption column to define the relation between C/s 0 and time. Rectangular isotherm is used to explain the equilibrium state between adsorbate and sorbent. The quasi-chemical rate equation is applied to represent the … WebA theoretical fixed-bed model, known as the Bohart-Adams equation, was evaluated in simulating the experimental breakthrough curves.
