• The fractionation of the tritiated water (HTO) was examined during the crystallization of hydrates, such as (COOH)<SUB>2</SUB>·2H<SUB>2</SUB>O, (COOK)<SUB>2</SUB>·H<SUB>2</SUB>O, Cu(HCOO)<SUB>2</SUB>·4H<SUB>2</SUB>O, and Sr(HCOO)<SUB>2</SUB>·2H<SUB>2</SUB>O. The dilution of HTO in the organic salts was found to be comparable to that in inorganic salts observed previously. The fractionation of HTO was explained on the basis of an ionic process in an aqueous solution, and the crystal growth mechanism, in a way similar to that described in a previous paper. On the contrary, a considerable dilution was observed for oxalic acid dihydrate. The proton effect on the fractionation in both the ionic and dehydration processes was also discussed.
