adsorbv.

Brit.

/adˈzɔːb/,

/ədˈzɔːb/,

/adˈsɔːb/,

/ədˈsɔːb/, U.S.

/ædˈzɔrb/,

/ædˈsɔrb/

Origin: Formed within English, by derivation; perhaps modelled on a German lexical item. Etymons: ad- prefix, absorb v.

Etymology: < ad- prefix + -sorb (in absorb v.), after either German adsorbieren (1869 or earlier) or adsorption n.

Chemistry.

1. transitive. Of a substance or body (typically a solid): to collect and hold on its surface (molecules of a gas, liquid, or solute). Frequently in passive. See also adsorption n.

adsorb1871

1871 London, Edinb. & Dublin Philos. Mag. 4th Ser. 70 374 The influence of the vapour adsorbed or condensed on the free surface of the drops naturally manifests itself more plainly in air than in the air-bubbles described in the experiments of §12.

1895 G. M'Gowan tr. W. Ostwald Sci. Found. Analyt. Chem. ix. 141 Potash and soda cannot be taken for this, for ferric hydroxide adsorbs these abundantly, and it is impossible to get rid of them entirely by washing.

1923 Discovery Sept. 231/2 Impurities deposited on or adsorbed by the crystals.

1928 W. A. Caspari Struct. & Prop. Matter ii. 37 Some charcoals will adsorb hundreds of times their bulk of gas.

1964 L. H. Van Vlack Elements Materials Sci. (ed. 2) xii. 350 The (CrO₄)²⁻ ions are adsorbed onto the anode surface, and in effect isolate it from further anodic reactions.

1988 A. M. Silverstein Hist. Immunol. xii. 317 Excess antibody (or antigen) is adsorbed to the plastic microplate, washed, and then treated with the test sample.

2002 G. V. Chilingar et al. Origin & Predict. Abnormal Formation Pressures x. 251 Base-exchanging clays suspended in electrolyte solutions adsorb a certain amount of fresher water, which is bound in double layers around each clay particle.

2. intransitive. Of a substance: to become bound to a surface with which it is in contact; to undergo adsorption. Chiefly with on (to), to.

1946 A. Nelson Princ. Agric. Bot. ix. 236 All substances which reduce the surface tension of a liquid adsorb at its air/liquid interface.

1974 Nature 8 Mar. 126/1 Caesium-137..does not adsorb significantly on to sedimentary material and is easily detected at very low concentrations.

1991 Day (New London, Connecticut) 14 July a4/4 The high numbers indicate the pesticides are ‘adsorbing’, or clinging, to soil particles.
