| 摘 要： | 软硬酸碱(HSAB)原理是六十年代美国化学家Pearson首先提出的。这一原理的提出,本是经验总结,然而许多研究者根据酸碱的一些基本性质,如电负性、电离势、电子亲合势、离子势等,提出了几种酸碱软硬度的定量标度,使之具有理论意义,从而定量或半定量地说明碱酸的反应性及其他性质。

| Abstract: | Application of the principle of hard and soft acids and bases(HSAB) to salting-out effect in solvent extraction by neutral extractants is discussed in this paper. The salting-out effect of cations is a function of their classification in "types of acid". The salting-out effect of the hard acid cations increases with the increasing of PA. Hard acid and borderline acids have different mechanisms in salting-out effect. The salting-out effect of Li+ and H+ is also discussed in the present work. |
