Adsorbent material is a substance that attaches molecules or particles to its surface, commonly used in industries such as water treatment, air purification, and gas separation. There are several synonyms for adsorbent material, such as adsorbent media, adsorptive agents, and sorbent materials. Some specific examples of adsorbent materials include activated carbon, silica gel, zeolites, and alumina. These materials are chosen based on their ability to selectively bind the target contaminant from the fluid or gas stream being treated. Adsorbent materials play a crucial role in removing pollutants and impurities from various industrial processes, improving the quality of the final product.
