Abstract
CONSIDERABLE interest has recently been focused on the suitability of using krypton adsorption isotherms at liquid air temperatures for the determination of the surface area of solids. From the isotherms the monolayer volume, v m, which can be converted to surface area using the effective cross-sectional area of an adsorbed krypton atom, is obtained by the Brunauer–Emmett–Teller method1. This method generally yields a linear plot of p/v(p 0 − p) against p/p 0 (v = volume adsorbed at an equilibrium krypton pressure, p ; p 0 = s.v.p. of krypton at the adsorption temperature) in the range of relative pressure, p/p 0, 0.05–0.35.
