✦ Synopsis

The chromatographic retention of H and D atoms has been observed in a quartz tube using argon as a carrier gas for D and six different gases for H. The results give equilibrium constants for the reversible adsorption of H and D on quartz as well as the rates of desorption. Self-consistent conclusions can be drawn from the data. The adsorption energy appears to be ca. 50 kJ mol-' indicating weak chemisarption. The observations are consistent with vibration frequencies on the surface of around 700-900 cm-' for D and around 1000-1300 cm-' for H. It appears that only a fraction of the surface atoms (ca. lo-') act as adsorption sites.
