Densities, Excess Molar Volumes and Excess Refractive Indices for Binary Solutions of D₂O and H₂O

Heavy water is an important industrial chemical for nuclear power generation from natural uranium, precursor for tritium, required for fusion power generation and an important chemical and biochemical tracer. Its separation from natural or synthetic D₂O–H₂O binary solutions is highly energy intensive. Therefore for development of chemical and physiochemical processes for its separation, physical properties of binary solutions of D₂O and H₂O are important. In this study, density, excess molar volume, refractive indices and related properties are reported for D₂O–H₂O binary solutions.
