Adsorption capacity is typically measured using adsorption isotherms, which plot the amount of adsorbate on the catalyst surface as a function of pressure or concentration at a constant temperature. Common techniques include:
- BET Method: Utilizes nitrogen adsorption to measure the surface area and pore size of the catalyst. - Gravimetric Analysis: Measures the change in weight of a catalyst as it adsorbs a substance. - Volumetric Methods: Involve measuring the volume of gas adsorbed at different pressures.
