Adsorbents are materials that have the ability to attract and hold particles or molecules on their surface. These materials are commonly used in a range of industrial and medical applications. There are several synonyms for the word "adsorbents," including sorbent, absorbent, desiccant, and dehumidifier. Sorbent is a broad term that encompasses both adsorbents and absorbents. An absorbent material is one that can take in and hold a substance within its structure, while a desiccant is a material that extracts moisture from the surrounding environment. A dehumidifier is a device that uses adsorbents or desiccants to remove excess moisture from the air.
