different and had aspects that seemed more similar to those of the 25 C Co(salen) curves than to either of the other Co(fluomine) curves. Much like the 25 C O2 sorption curves for the Co(salen) material, the 60 C curves measured for the Co(fluomine) material contained a similar hysteresis. The adsorption curve had a similar 0.2-atm O2 pressure “threshold”; but the curve had a less sharp rise to the final capacity. Unlike the 25 C and 0 C Co(fluomine) curves, the O2 was desorbed at low pressure, again similar to the Co(salen). It is interesting that the greatest O2-binding capacity (of these three temperatures) is for that measured at 25 C. One explanation for this was the possible slow kinetics of binding at 0 C. Adsorption on Co(fluomine)-LSX. Co(fluomine) was immobilized on the surface, or within the pore structure, of several materials. The O2 and N2 adsorption and desorption isotherms, measured at 25 C, for Co(fluomine)-LSX and for Co-LSX are shown in Figure 5. The isotherms for the Co-LSX zeolite are typical Langmuir-type isotherms. The curves for the immobilized complex on the zeolite are somewhat similar to those of the free Co(fluomine), but with a much lower capacity. As with the Co(fluomine), O2 was strongly bound at very low pressures; but unlike the free material the immobilized material did not immediately attain the full capacity. Rather, the O2 uptake steadily increased. The capacity at 1 atm for this material was 0.15 mmol/g. Assuming that only two Co(fluomine) molecules may be placed in the zeolite supercage and given that other sites (such as those in the beta cages and hexagonal prisms) are too small to accommodate the complex and are sterically inaccessible to O2, the maximum O2 capacity expected is 0.57 mmol/g for a 1:1 (O2:Co2+) adduct and 0.29 mmol/g for a 1:2 (O2:Co2+) adduct. Because the zeolite itself has some O2-binding capacity, there is some enhancement of the 163PDF Image | PSA USING SUPERIOR ADSORBENTS
