desorb1924

1924 Proc. Royal Soc. A. 106 64 (heading) The energy required to desorb the gas-film.

1924 Proc. Royal Soc. A. 106 67 Some gases..are desorbed from tungsten, etc., with practically zero latent heat.

1937 Nature 10 July 48/1 Tswett conceived the idea of making the solution flow in one direction..through a column of the adsorbent, so that the adsorbed material might afterwards be desorbed, or ‘eluted’, by the same or some other more suitable solvent.

b. intransitive. Of a substance, etc.: to leave the surface upon which it is adsorbed (and pass into).

ΚΠ

1964 New Scientist 26 Mar. 828/2 The free radicals were left to accumulate on the surface, from which they ‘desorbed’ back into the chamber.

1967 E. L. Pace in E. A. Flood Solid-Gas Interface I. iv. 123 The desorption was accomplished by allowing the gas to desorb into a measured volume with the simultaneous application of heat.
