adsorption capacity

Adsorption capacity refers to the ability of a material to attract and hold onto molecules from a gas or liquid on its surface. Imagine a sponge soaking up water; the sponge's ability to absorb depends on its size and porosity. Similarly, materials like activated carbon or zeolites have surfaces that can attract various substances, making them useful for purification, filtration, and other applications. The higher the adsorption capacity, the more substances the material can hold, allowing it to effectively remove impurities or capture specific molecules from its environment.
