Good gas chromatographic separation of H/sub 2/ HD, and D/sub 2/ was obtained with alumina coated with ferric oxide and partially deactivated with CO/ sub 2/. The range of D/sub 2/ concentration determinable in this way with ca. 0.2% deviation is 1 to 99%; HD can be detected in H/sub 2/ or D/sub 2/ at 0.01% or less. Alumina with adsorbed O/sub 2/ was also found to be good for b 2/ restores ortho-para separation, whose peaks interfere with the above separation. It appears that ferric oxide and O/sub 2/ produces rapid ortho-para equilibration, thus facilitating H/sub 2/-HD-D/sub 2/ separation. Limiting isosteric heats of adsorption on alumina and differences between the heats of adsorption of ortho-para isomers are reported. (D.L.C.)
