The Gas-Solid Interface the adsorption of nitrogen, argon, neopentane, sulfur dioxide, carbon dioxide and sulfur hexafluoride on rhombic sulfur

Sollberger, Frédéric ; Stoeckli, Fritz

In: Helvetica Chimica Acta, 1974, vol. 57, no. 8, p. 2327 - 2331

Physical adsorption of the title compounds on rhombic sulfur of 0.4 to 0.5 m2/g is reported. The isotherms are of type II for N2, Ar and C5H12, of type III for SO2 and CO2, and linear for SF6. There is no hysteresis. The method of Ross & Olivier shows that the surface is relatively heterogenous (γ = 17).... More

    Summary
    Physical adsorption of the title compounds on rhombic sulfur of 0.4 to 0.5 m2/g is reported. The isotherms are of type II for N2, Ar and C5H12, of type III for SO2 and CO2, and linear for SF6. There is no hysteresis. The method of Ross & Olivier shows that the surface is relatively heterogenous (γ = 17). Isosteric heats of adsorption and c values of the B.E.T. equation are also reported.
