Estimation of the Separation Coefficient of Oxygen Isotopes in Aqueous Salt Solutions

The theoretical possibility of determining the separation coefficients of oxygen isotopes for systems containing hydrated halogen ions and metal cations is considered. The temperature dependence of the separation coefficient for aqueous systems containing urea molecules has been obtained. It is found that the contribution of cations and anions to the separation of oxygen isotopes is present, but it is characterized by small values.
