Abstract

By using slow damped oscillations of a torsional pendulum, it is possible to determine the mass adsorbed on the surface of a porous sorbent without buoyancy effects from the frequency and the logarithmic decrement of the pendulum motion. In principle, it is then possible to determine directly the buoyancy-related volume Vas of the sorbent/sorbate system by combining the results with gravimetric measurements.

Measurements with a preliminary testing pendulum are presented for N2 and CH4 on the activated carbon Norit R1 Extra at ambient temperature in the pressure range 0<p<0.5 MPa. Values for Vas calculated from these measurements and gravimetrically determined data are presented and discussed to a certain extent.
