摘要：
Dissolution behavior of cesium chloride in the mixture of imidazolium based ionic liquids ([Cnmim]Br (n=2,4,6,8)) and water was studied by density and refractive index simultaneous method. The density and refractive index of CsCl+[Cnmim]Br (n=2,4,6,8)+H2O ternary systems with different component were measured at T=(288.15, 298.15 and 308.15) K. The highest concentration of CsCl in [Cnmim]Br (n=2,4,6,8) aqueous phase was obtained by correlating the density and refractive index data. The results indicated that the precipitation of cesium bromide was found in [Cnmim]Br (n=2,4,6,8) aqueous solution when adding cesium chloride. The complex decomposition reaction occurred in the system. The highest concentration of CsCl in the saturated solution decreased with the increasing of ionic liquid concentration at the same temperature. For a constant mass fraction of ionic liquid, the order of the highest concentration of CsCl in [Cnmim]Br (n=2,4,6,8)+H2O mixtures was [C2mim]Br<[C4mim]Br<[C6mim]Br<[C8mim]Br. Furthermore, the concentration of CsCl in saturated solutions increased with the system temperature increasing. The empirical equation was used to fit the concentration of CsCl in saturated solutions. It was found that empirical equation could qualitatively represent the equilibrium behavior. In addition, the density and refractive index of the saturated solutions were determined for describing the relationship between the physical property and the solution composition. © Editorial Office of Chinese Journal of Rare Metals.
