摘要
本文用液上空间气相色谱法测定了由TBP-稀释剂、UO_2(NO_3)_2·2TBP-稀释剂(稀释剂为nC_8H_(14),nC_7H_(16),nC_8H_(18),C_6H_6,C_6H_(12),CCl_4,CHCl_3)所组成的20个二元体系和7个三元体系中组分活度系数,并由作者自行从分子径向分布函数与阻尼振荡相类比而推导得出的DORDF方程进行关联,从而回归得到9种化合物的分子作用参数。由这些二元体系获得的参数可用以推算相应的三元体系。文中还将DORDF方程与其它活度方程进行了比较。
In this paper, the DORDF equation, deduced from damping oscillation and radial distribution function, is used to correlate the experimental activity coefficient data for 20 binary systems, including TBP and UO2(NO3)2·2TBP and using nC6H14, nC7H16, nC8H189 C6H6, C6H12, CC14, CHC13 as diluents. The energy parameters for 9 compounds from binary systems are regressed.The activity coefficient values for ternary systems can be predicted successfully without additional parameters. Some other activity equations are also compared.
