Interpretation by the Solvophobic Theory on the Linear Additive Representation of the Logarithm of Ion-Pair Extraction Constant with Individual Contributions of Cation, Anion, and Organic Solvent

Autor: Kanji Miyabe, Katsumi Goto, and Issei Kasahara, Shigeru Taguchi

Publikováno v: The Journal of Physical Chemistry B. 104:8481-8490

A theoretical basis was given for the linear additive representation of the logarithm of ion-pair solvent extraction constant (Kex) in terms of logarithmic values of three individual extraction constants (Kcation, Kanion, and Ksolvent) for cations, a
