  • Another method of removing contaminants from the soil is thermal desorption.

    Academic text (1995)
  • Since desorption requires energy to break surface bonds, temperatures as high as 900 K may be needed.

    Academic text (1998)

desorption singular

Morphology

desorption = desorb (semi-transparent) = de + sorb + ion

The noun is regularly formed from 'desorb' + '-ion', but 'sorb/desorb/sorption' are specialized scientific terms that may be unfamiliar to general learners.

Etymology

Desorption comes from the prefix de- meaning 'remove' and the root sorb, seen in absorb, meaning 'to take in' or 'stick to'. So, desorption is the process of 'releasing' something that was stuck to a surface back into a gas or liquid.
