Summary
It was proved that the partial adsorbed quantities can be calculated from the individual adsorption isotherms. This calculation can be carried out by equations which take into' account the energetical heterogeneity of the surface of adsorbent as well. Thus, the partial isotherms equations which can be applied are as followsV A (p A ,p B ) =p A /[b a + (p A +b AB p B )m]1/m andV B (p A ,p B ) =p B /[b B + (p B +b BA p A )m]1/m wherep A andp B are the partial equilibrium pressures, whileb A ,b B andm are constants which can be determined on the basis of the individual isotherms.
Zusammenfassung
Es wurde nachgewiesen, daß die partialen Adsorbatmengen aus den individuellen Isothermen berechnet werden können. Die Berechnung kann mit Hilfe von Gleichungen durchgeführt werden, die auch die energetische Inhomogenität der adsorbierenden Oberfläche berücksichtigen. Benutzt werden die Gleichungen: VA(pA,pB) = pA/ [bA + (PA + bABpB)m]1/m und VB(pA,pB) pB/[bB + (pB + bBApA)m]1/m, wop A undp B die Gleichgewichtspartialdrucke undb A ,b B undm die aus den individuellen Isothermen zu bestimmenden Konstanten darstellen.
