physisorbv.

Brit.

/ˈfɪzᵻsɔːb/, U.S.

/ˈfɪzəˌsɔrb/

Origin: Formed within English, by compounding. Etymons: physical adj., adsorb v.

Etymology: < physi- (in physical adj.) + -sorb (in adsorb v.), after physisorption n. Compare earlier chemisorb v., and also physisorbed adj.

Chemistry.

transitive. To collect by physisorption. Also intransitive.

1959 Jrnl. Physical Chem. 63 518 The second isotherm gives the amount of CO physisorbed.

1967 Surface Sci. 6 2 A substance with a vapor pressure of 1 × 10⁻² Torr or more will not physisorb on graphite in quantities approaching a monolayer if its ambient pressure over the graphite is 1 × 10⁻⁴ Torr or less.

1999 Chem. & Industry (Nexis) 20 Sept. 702 Activated carbons are relatively ineffective at physisorbing gases, so a chemisorption process must be used in the filter to trap and/or destroy them.

2001 Solid State Technol. (Nexis) 44 125 One set is used when the amount of adsorbed moisture exceeds a monolayer and the water is physisorbed on top of other layers of water.
