Morphology
desorb = adsorb (opaque) = de + sorb
Although formed by the prefix 'de-' + the combining form 'sorb', both the root and the related verb 'adsorb' are specialized scientific items unfamiliar to average B1 learners.
Etymology
The word desorb comes from de- 'away' plus sorb 'to suck in', the same root you see in absorb and the everyday idea 'suck'. So to desorb is to let a substance be 'sucked away' from a surface, which fits its modern scientific meaning.
