WebSorption behavior describes the ability of a hygroscopic product to absorb or release water vapor from or into the air until a state of equilibrium is reached. Adsorption means uptake of water vapor. Desorption means water vapor release. A sorption isotherm is the graphic representation of the sorption behavior of a substance. WebApr 10, 2024 · The term hygroscopic refers to a matter's ability to hold, adsorb and attract water from the surrounding environment. This process of absorption usually occurs near ambient or room temperature. This term originates from a 1790s device called a hygroscope, which was made to measure humidity. It did this by measuring changes in …
