Is ion exchange a adsorption process?
Adsorption and ion exchange are sorption operations, in which certain components of a fluid phase are selectively transferred to insoluble particles. Adsorption processes use the natural tendency of liquid or gas components to collect at the surface of a solid material.
What is ion exchange adsorption?
The adsorption results in the formation of a molecular layer of the adsorbate on the surface. Often an equilibrium concentration is rapidly formed on the surface and is sometimes followed by a slow diffusion into the particles of the adsorbent. Ion exchange is an exchange of ions between a liquid and a solid phase.
Which process is involved in adsorption process?
The process of adsorption involves separation of a substance from one phase accompanied by its accumulation or concentration at the surface of another. The adsorbing phase is the adsorbent, and the material concentrated or adsorbed at the surface of that phase is the adsorbate.
What is common between selective and ion exchange adsorption?
Depending on the character of the process two types of adsorption of strong electrolytes are distinguished: selective adsorption and ion exchange adsorption. A common feature for both types of adsorption is the fact that in both cases the formation of a double electric layer in the solid-liquid interface is present.
What is ion exchange mechanism?
Ion exchange is a chemical reaction in which free mobile ions of a solid, the ion exchanger, are exchanged for different ions of similar charge in solution. The exchanger must have an open network structure, either organic or inorganic, which carries the ions and which allows ions to pass through it.
What is the mechanism of ion exchange process?
How can you explain the application of ion exchange adsorption in water treatment?
Ion exchange is a water treatment method where one or more undesirable ionic contaminants are removed from water by exchange with another non-objectionable, or less objectionable ionic substance.
