In this research, the effect of adding MIL-100 (Fe) MOFs on the PEBAX membranes has been scrutinized in two grades of 1657 and 2533. Initially, the intended membranes were synthesized by the solutioncasting method. Then, the XRD and SEM were applied to deliberate the in uence of adding to the structure of both types of membranes. In consequence, the separation function of the pair gases of CO 2 /CH 4 CO 2 /N 2 and CO 2 /O 2 and their permeability were considered at the pressure of 3.5 bar and temperature of 25°C. Eventually, their function was compared by Robeson diagrams of 1991 and 2008. The comparison results by Robeson diagrams indicated that the PEBAX1657/MIL-100 (Fe) and PEBAX2533/MIL-100 (Fe) membranes containing 5 wt.% of MOF represent more suitable performance in separating CO 2 /CH 4 in comparison with the axis of the Robeson diagram. However, their function for separating the aforementioned gases requires more modi cations.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
