  "term": "Desorption",
  "field": "Chemistry",
  "definition": "The physical process where a substance is released from or through a surface, representing the reverse of sorption (adsorption or absorption). This release of adsorbed or absorbed species from a solid or liquid phase into a gas or liquid phase can be induced by heating, reducing pressure, or chemical displacement. The rate of desorption is a key parameter in catalysis, surface science, and chromatography.",
