Kemosorb

Kemosorb is a term that refers to the process of chemical absorption, specifically where a substance, known as the sorbate, is chemically bonded to another substance, the sorbent. This interaction is distinct from physical adsorption, where the sorbate adheres to the sorbent through weaker intermolecular forces. In kemosorption, a chemical reaction occurs at the surface of the sorbent, forming a stronger, often irreversible bond.

This process is fundamental in various industrial and scientific applications. For example, in gas purification, kemosorbents are used to remove specific gases from a mixture by chemically reacting with them and trapping them on the sorbent material. This is crucial in applications like air filtration, industrial emissions control, and the production of high-purity gases.

The effectiveness of kemosorption depends on factors such as the chemical nature of the sorbate and sorbent, temperature, pressure, and the surface area of the sorbent. Common sorbent materials include activated carbon, zeolites, and various metal oxides, chosen for their specific chemical properties that allow for targeted reactions. Understanding the principles of kemosorption is vital for designing efficient separation and purification systems in diverse fields.
