Meaning and Definition
The general process by which one substance (the sorbent) takes up and holds another (the sorbate), encompassing both absorption and adsorption.
A physical or chemical process occurring at an interface where atoms, ions, or molecules from a gas, liquid, or dissolved solid adhere to or are incorporated into a solid or liquid material. It is a key concept in separation science and materials chemistry.

Common Mistakes When Using “sorption”
- Using 'sorption' as a verb (e.g., 'The material sorbs the chemical' is correct, but 'sorptioning' is not).
- Confusing 'sorption' with 'absorption' (e.g., using it for the uptake of nutrients by the body).
- Spelling as 'sorbtion' or 'sorpsion'.
FAQ
Frequently Asked Questions
Sorption is the umbrella term. Absorption refers to uptake into the bulk or volume of a material (like a sponge soaking up water). Adsorption refers to adhesion onto the surface of a material (like a gas sticking to charcoal).
No. It is a highly specialised scientific term. You will only encounter it in technical literature related to chemistry, environmental engineering, or materials science.
No. The verb form is 'to sorb' (e.g., "the material sorbs gases"). 'Sorption' is exclusively a noun.
Yes. Think of it as a general word for when one substance 'sticks to' or 'soaks into' another substance, often to remove it from a mixture.
Sorption is usually technical/scientific in register.
Sorption: in British English it is pronounced ˈsɔːp.ʃən, and in American English it is pronounced ˈsɔːr.pʃən. Tap the audio buttons above to hear it.

Memory Aids
Mnemonic
Think of a SPONGE (sorPtion) soaking up water – it holds it in. "Sorption" is like a sponge's action on a molecular level.
Conceptual Metaphor
THE SOLID IS A SPONGE / THE INTERFACE IS A TRAP.
