Explanation:
In other words, adsorption is a mass transfer process that includes the accumulation of substances at the interface of two phases, such as the liquid–liquid, gas–liquid, gas–solid, or liquid–solid interface (Dąbrowski, 2001). The substance being adsorbed is the adsorbate, and the adsorbing material is the adsorbent.
Adsorption is a surface process that leads to transfer of a molecule from a fluid bulk to solid surface. This can occur because of physical forces or by chemical bonds. Usually it is reversible (the reverse process is called desorption); then it is responsible not only for a subtraction of substances but also for release. In most of the cases, this process is described at the equilibrium by means of some equations that quantify the amount of substance attached on the surface given the concentration in the fluid. These equations are called isotherms (the most famous are the Langmuir and the Freundlich equations) because of the dependence of their parameters on the temperature, which is one of the most important environmental factors affecting adsorption. Adsorption has a fundamental role in ecology: it regulates the exchanges between geosphere and hydrosphere and atmosphere, accounts for the transport of substances in the ecosystems, and triggers other important processes like ionic exchange and enzymatic processes.
