摘要：结合水溶液粘度的溶质聚集模型和拟二元方法,作者提出了一个适用于水-有机溶剂-盐三元溶液粘度关联的拟二元溶质聚集模型(PSAV),能够成功地应用于以盐饱和与不饱和水溶液粘度的关联,平均相对偏差约1.0%,比作者早先提出的拟二元局部组成模型(平均相对偏差为2～5%)有较大的改善。对于盐不饱和溶液,模型参数随浓度和温度呈有规律的变化。
Based on the pseudobinary method and solute aggregation model of aqueous solution, a pseudobinary solute aggregation model for correlating the viscosity of water-organic solvent-salt solution is established. The model has been tested for ternary aqueous solutions saturated or unsaturated with salt. The average relative deviation is about 1.0%. The results are better than the pseudobinary local composition model presented early by authors. The model parameters vary regularly with the concentration of salt and temperature for unsaturated solution.
