摘要	On the basis of impregnation method, several stationary phases were prepared using gamma-Al2O3 with the solution of transition metal salts and the breakthrough curves of gas chromatograph for H-2 isotopes were analyzed under the temperature of liquid nitrogen. The effects of carrier gas, flow rate and doping concentration on the separation performance for H-2 and D-2 were systematically investigated. The overall results showed that the surface areas and adsorptive capacities of modified gamma-Al2O3 were slightly lower than unmodified one while the separation performance and symmetry of chromatographic peaks of the former were more excellent. In addition, the chromatographic peaks of ortho- and para-H-2 were no longer separated and the retention time shortened to half on columns of modified gamma-Al2O3. All the magnetic transition metal ions modified gamma-Al2O3 did very well for the separation of H-2/D-2 under the conditions of neon as carrier gas with a flow rate of 60 mL/min and column lengths of 1.0 m and injection amounts of 0.1 mL. Especially, the MnCl2 modified gamma-Al2O3 exhibited the best performance for separating H-2/D-2 with an optimum doping concentration of 20 wt%.
