A material that collects and holds particles or molecules on its surface, often used to capture gases or liquids.

Adsorber is formed from "ad-" (meaning to) and "sorbere" (meaning to suck in or absorb). The word describes a substance that attracts and holds particles on its surface, effectively sucking them in.
Think of something that 'sucks in' particles ('sorbere') to its surface, which is what an adsorber does.
