ADSORPTION

The process of adsorption sees the separation of liquids, gases, colloids or suspended matter from a medium by adherence to the surface or pores of a solid. So in essence, the molecules of these elements will stick to the surface of a solid or liquid, rather than entering it. The molecules are only loosely held by the surface and are easily dropped off

Adsorption is able to be reversed and is responsible for not just less matter but also for release. In most cases, adsorption is explained throughout the equilibrium through equations that estimate the degree of matter latched on the surface in correspondence to the concentration in the fluid. One example of the adsorption process is the using of charcoal in gas masks to eradicate impurities (poison) from the air supply.

Adsorption can either be naturally physical or chemical. Chemical adsorption usually occurs during higher temperatures than physical adsorption. It also has a much slower process than physical adsorption, involving more energy usage, like the majority of chemical reactions.
