Use Adsorption to simulate the interaction between a solute moving through the structure and reactive porous voxels. Adsorption-based processes are widely used to remove contaminants and odors in various everyday applications. These processes often rely on materials with large internal sub-micron surfaces, such as activated carbon or zeolites.

There are two approaches available for simulating the solute movement through the structure:

1. Tracking tracer particles based on the Track Particles & Molecules command, or
2. Simulating the movement of a concentration field based on the Transport Concentration Field command.

The simulated solute distributions are then used to compute local adsorption reactions in reactive porous voxels. Within the porous active zone, the governing adsorption equations are solved based on the transported concentration and the equilibrium concentrations. Equilibrium concentrations are computed based on adsorption isotherms that you define. You can choose to use one of multiple isotherm models or enter measured values directly.

The results include the breakthrough behavior, the overall adsorption uptake, and the local adsorption distribution inside the reactive porous zones over time. These insights help determine the optimal usage durations of adsorbent materials and guide design adjustments, such as changes to the geometry, to maximize the efficiency and sustainability of valuable materials.
