Abstract
AbstractThe 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−1 indicating weak chemisorption. The observations are consistent with vibration frequencies on the surface of around 700–900 cm−1 for D. and around 1000–1300 cm−1 for H. It appears that only a fraction of the surface atoms (ca. 10−2) act as adsorption sites.
