摘要
将微扰理论和平均球近似相结合,对纯溶剂采用软球直径和色散能参数(σ和ε/k)两个可调参数,对电解质仅采用阳离子软球直径(σ+)作为唯一的可调参数,将36种纯极性溶剂和40种强电解质水溶液的密度进行了关联,结果较为满意.
Correlation of densities for electrolyte aqueous systems is developed by use of the mean spherical approximation (MSA) and the perturbation theory For pure polar solvents only two adjusting parameters ( σ and ε/k) are needed and for electrolyte aqueous systems only the soft diameters of cations (σ+) are treated as the adjustable parameters The densities of 36 pure polar solvents and 40 electrolyte aqueous systems are correlated The correlation accuracy is satisfactory
