从理论上考虑了离子在W和O之间的分配过程，提出了一种测定高亲水性金属离子在高浓度H+存在下从水溶液W转移到有机溶液O的标准吉布斯自由能ΔG°tr的方法。通过与伏安法测定的W|O界面离子转移的ΔG°trof Mg~(2+)进行比较，验证了该方法的有效性。被检测的O是硝基苯(NB)和1，2-二氯乙烷(DCE)。用该方法测定了从酸性W到Nb的NpO2+、UO22+、NpO22+和PuO22+的ΔG°T。
A method to determine the standard Gibbs free energy for the transfer, ΔG°tr, of a highly hydrophilic metal ion from an aqueous solution, W, in the presence of high concentration of H+to an organic solution, O, was proposed based on the theoretical consideration of the distribution process of ions between W and O. The usefulness of the proposed method was verified experimentally by comparing ΔG°trof Mg2+determined by the method with that obtained by voltammetry for the ion transfer at the W|O interface. The O examined were nitrobenzene (NB) and 1,2-dichloroethane (DCE). By applying the proposed method, ΔG°trof NpO2+, UO22+, NpO22+and PuO22+from an acidic W to NB were determined.
