Tritium enrichment or depletion by water distillation was investigated using a glass column of 32 cm in height packed with silica-gel beads of 3.4 mm in average diameter. The total separation factor of the silica-gel distillation column, alpha(H-T), was compared with those of an open column distillation tower and of a column packed with stainless-steel Dixon rings. Depletion of the tritium activity in the distillate was enhanced by isotopic exchange with water adsorbed on silica-gel beads that have a higher affinity for HTO than for H2O. The value of alpha(H-T)-1 of the silica-gel distillation column was about four times larger than that of a column without any packing and about two times larger than that of the Dixon-ring column. The improvement of alpha(H-T) by the silica-gel adsorbent indicated that the height of the distillation-adsorption column becomes shorter than that of the height of conventional distillation columns.
