The adsorption experiments of 1,1,2-trichloro-2,2,1-trifluoroethane on
dry activated carbon pellet were carried out at 298 K. For low concen
trations of 1,1,2-trichloro-2,2,1-trifluoroethane; the Langmuir equati
on was well correlated by experimental data. In this study, the effect
s of presorbed water upon the adsorption capacity of 1,1,2-trichloro-2
,2,1-trifluoroethane by a pellet-type carbon adsorbent are considered.
It was found that the large decrease in adsorption capacity was cause
d by the presorbed water.
