“…Any Henry constants that were reported in the collected literature were recorded and compared to our virial-derived values. Only the studies of Miller, Gorbunov et al, Golipour et al, Li and Tezel, and Vashchenko and Serpinskii were explicit in presenting Henry’s law constants. The remaining papers presented parameters derived from one of eight isotherm models; these were Langmuir, Langmuir–Freundlich, virial, Sips, Toth, multisite Langmuir, Ruthven’s statistical isotherm, and a linear isotherm if appropriate.…”
