Comparison between Henry’s type and Langmuir isotherms of xenon sorption in shale at 0 \(^{\circ }\)C. (a) Langmuir isotherm fits well with experimental data in the full concentration range (\(0 \le c \le 55\) [mol m\(^{-3}\)]). (b) Henry’s type isotherm approximates experimental data in the low concentration range (\(0 \le c \le 7\) [mol m\(^{-3}\)]). The solid curve (blue) represents the Langmuir fit while dashed (magenta) and dotted (black) lines are the Henry’s type fit and the linearized Langmuir fit when \(b'~c\ll 1.\)
