What is Adsorption?
Adsorption is when a gas or liquid fluid phase containing one or more contaminants (adsorbates) comes in contact with the surface of an activated solid (adsorbent) that has the property of attracting the contaminants present in the fluid phase. The process of concentrating the adsorbates on the solid surface is called adsorption and the reverse process is desorption or regeneration.
Adsorbents are characterized by polarity and surface area. Adsorption is physically caused by van der Waals forces and electrostatic forces between the contaminants you want to remove and the adsorbent surface. Surface area and the size of the micropores on the adsorbent determine the accessibility of the contaminants to the internal adsorbent surface. Adsorbents can be specifically engineered to eliminate certain molecules entering with precise pore size to allow specific contaminant entry.
There are a number of different adsorbents commercially available such as molecular sieves, silica gels, activated carbon, alumina, natural zeolites, etc. Each adsorbent has specific adsorption characteristics, when coupled with the precise pore size, provide very targeted contaminant removal.
