  "term": "Sorption",
  "field": "Chemistry",
  "definition": "A general physicochemical process by which one substance takes up or holds another, used when the specific mechanism is not known or when both absorption and adsorption are involved. Absorption involves the diffusion of a substance into the bulk of a liquid or solid phase, while adsorption is the accumulation of a substance at an interface. The term sorption provides a non-specific way to describe the overall phenomenon of a sorbate being retained by a sorbent.",
