Abstract

Abstract : A bimetal-functionalized zeolite of Cu–Fe/ZSM-5 is synthesized as the stationary phase material for an efficient chromatographic analysis of hydrogen gas isotopes. Abstract : Materials as stationary phase are crucial for the chromatographic analysis of hydrogen gas isotopes. In this study, a Cu–Fe/ZSM-5 zeolite with ion-exchanged Fe 3+ –Cu 2+ is prepared for H2 /D2 chromatographic analysis. High-resolution H2 /D2 separation is enabled within 4 min and their concentrations are quantitatively analyzed according to peak areas with high accuracy ( R 2 ≥ 0.999).
