For ease of comparison with other figures, qst is shown as a function of pressure, with pressure on a logarithmic scale; a visualization as a function of loading would deliver qualitatively analogous findings. Altogether, it is apparent that the affinity towards PCE is higher than towards TCE, and that the isosteric heats of adsorption increase with increasing loading. While the former observation is straightforwardly explained with the increased vdW interactions between PCE and the zeolites, the latter finding points to a prominent role of attractive guestguest interactions. However, it is also noteworthy that both the quantitative differences among the qst values obtained for TCE and PCE as well as the magnitude of the qst increase with pressure vary considerably, depending on the framework type.
