Chemisorption Superior Contaminant Removal Chemisorption plays a crucial role in air filtration, especially for removing harmful or unpleasant gaseous pollutants. It is a process where gas or vapor molecules chemically react with a sorbent or with reactive substances within it, binding the pollutants to the filter material. This process leads to the permanent breakdown of pollutants into harmless byproducts, unlike physical adsorption, which only traps molecules.
How Chemisorption Is Used in Air Filtration
Gases Optimally Adsorbed by Chemisorption Hydrogen Sulfide (H 2 S): A common component of sewage odors and industrial process gases. Sulfur Dioxide (SO 2 ): A major air pollutant. Nitric Oxide (NO): Another harmful gas. Formaldehyde: A toxic chemical. Ammonia: A pungent gas, often removed using chemisorbents specifically designed for amines and other basic compounds. Chlorine: A hazardous gas, where specialized chemisorbents convert it into harmless byproducts.
Targeting Specific Gaseous Contaminants Chemisorption is particularly effective for removing gases not optimally adsorbed by activated carbon alone.

CHEMISORPTION
Impregnated Activated Carbon Activated carbon, a common adsorbent, is often impregnated with chemical agents to enhance its effectiveness for chemisorption. These agents, such as acids, bases, or oxidizing chemicals like potassium permanganate, react with specific gases, leading to their chemical transformation and removal.
Dedicated Chemisorbent Media Specific chemisorbent media, often porous substrates like activated alumina, zeolite, or carbon, are engineered to target certain pollutants. These medias convert harmful gases into harmless materials trapped within the media.
Blended Media Combining different media, such as activated carbon and chemisorbents, is a common approach to achieve broad-spectrum gas removal in air filtration systems. These blends leverage the strengths of both physisorption and chemisorption to address various types of pollutants.
Examples of Chemisorbent Media Potassium Permanganate Impregnated Alumina: Commonly used to break down pollutants like formaldehyde, hydrogen sulfide, and sulfur dioxide. Sodium Permanganate on Alumina: Known for its high oxidation capacity Impregnated Carbon: Used to remove base pH gases, such as ammonia Alkali-Impregnated Carbon and Zeolite: Effectively removes acidic gases.
Chemisorbent Media Several specific chemisorbent media are used in air filtration. Chemisorption enhances air filtration by providing a chemical reaction that permanently removes specific gaseous pollutants, making it a critical component of modern air purification systems, especially in industrial and commercial settings.
