THERMODYNAMIC ISOTOPE EFFECTS OF TRITIUM IN HYDROXYL AND CARBOXYL GROUP

Distribution of tritium atoms in aqueous solutions of organic substances being used as food additives (ascorbic acid, citric acid, and maleic acid as trans-isomer of fumaric acid) has been studied experimentally. As it follows from the results obtained tritium atoms have a trend to be concentrated in the solutes as well as in their hydrate shells. Corresponding isotope equilibrium constants have an order of about 1.7.
