Oxygen adsorption isotherms

Ghetta, V., Fouletier, J. and Chatain, D., Oxygen adsorption isotherms at the surfaces of liquid Cu and Au-Cu alloys and their interfaces with A1203 detected by wetting experiments , Acta. Mater., 1996 44(5) 1927-1936. 

Oxygen adsorption isotherms, in the experimental region, is Henry type isotherm (Figure 8). Table IV gives Henry constants. 

Oxygen Adsorption Isotherms. Oxygen adsorption isotherms on the Cab-O-Sil surface at various temperatures up to —47 °C were measured. The isotherms obtained followed Langmuir adsorption at the temperatures examined. Theoretical treatment of the oxygen adsorption isotherm data (27) yields a heat of adsorption of 3.54 kcal/mol (14.8 kj/mol) and the assimilation times of 23.2, 44.1, 99.5, and 238 ps at —47, —64, —80, and —98 °C, respectively.
