[Analysis of hydrogen isotopes by gas chromatography using a MnCl coated -AlO capillary packed column].

The conventional packed column gas chromatographic analysis of hydrogen isotopes has low column efficiency, broad peak and long retention time. In this work, a -AlO with MnCl coated capillary packed column was tested at cryogenic temperature. The systematic column efficiency analysis and the hydrogen isotopes analytical technique research had been carried out.

Preparation and characterization of hydrophobic Pt-Fe catalysts with enhanced catalytic activities for interface hydrogen isotope separation.

Liquid phase catalytic exchange reactions are mainly used for separation of hydrogen isotopes from liquid water. Based on the carbon-supported Pt and Pt-Fe catalysts, different hydrophobic Pt and Pt-Fe catalysts were fabricated for use in such reactions. The characterization results indicated the Pt-Fe alloy was formed in the Pt(3)Fe/C catalyst prepared using a citric-acid-assisted NaBH(4) reduction method (CA-NaBH(4)).
