M. Kazayawoko et al., THERMODYNAMICS OF ADSORPTION OF N-ALKANES ON MALEATED WOOD FIBERS BY INVERSE GAS-CHROMATOGRAPHY, Journal of colloid and interface science, 190(2), 1997, pp. 408-415
The adsorption of n-heptane, n-octane, n-nonane, and n-decane on untre
ated wood fiber and wood fiber treated with maleated polypropylene was
studied by inverse gas chromatography (IGC) at infinite dilution or z
ero surface coverage. The specific retention volume increased with inc
reasing probe chain length, decreased with increasing column temperatu
re, and increased with increasing maleated polypropylene concentration
. The enthalpy of adsorption increased with increasing chain length of
the probe vapors. The enthalpy of adsorption remained constant after
the treatment of wood fiber. The London dispersive component of the su
rface free energy decreased with the column temperature and showed no
dependency with either the type of wood fiber or the maleated polyprop
ylene concentration. (C) 1997 Academic Press.
