WHAT ARE THE APPLICATIONS OF ABSORPTION ??
Answers
Absorbers are used in many segments of the CPI and other industries. The chemical industry uses absorbers to capture acid gases, such as hydrogen chloride and sulfur dioxide, which are released in various processing steps. The plating industry uses absorbers to capture the fumes from the plating tanks. The food industry eliminates odorous emissions with absorbers.
Adsorption :
1) Air pollution masks:
These consists of silica gel or activated charcoal powder, when dust or smoke are paused through them, those particles get adsorbed on the surface of these materials.
2) Separation of noble gases by Dewar’s flask process:
A mixture of noble gases of Ne, Ar, Kr is passed through Dewar’s flask in presence of heated coconut charcoal. Argon and Krypton gels adsorbed leaving Neon.
3) Purification of water:
By the addition of alum stone to the water, impurities get adsorbed on the alum and water gets purified.
4) Removal of moisture and humidity:
Moisture in the air is removed by placing silica gel on which water molecular gets adsorbed.
5) Adsorption chromatography:
It is used to separate pigments and hormone.
6) Ion exchange method:
In this method of removing the hardness of water, calcium and magnesium ions get adsorbed on the surface of ion exchange resin
7) In metallurgy:
In froth floatation process of concentration of ore, the particle gets adsorbed on the froth.
