Conclusions

  1. 1.

    The authors have investigated the influence of the pH of the aqueous phase on extraction of alkali elements by alkylphenol (AP), and have established that below pH 12.8 the extraction of water is slight, but increases with the pH.

  2. 2.

    The value of the hydrate numbers of the cations decreases on increase in their crystallochemical radius.

  3. 3.

    The influence of the cation concentration on the behavior of water has been investigated, and the cations have been placed in the order of their salting-out effect with respect to water.

  4. 4.

    Anions also exert a salting-out effect on water; the dependence of this effect on the anion radius has been determined.

  5. 5.

    The relation between the salting-out of water from the organic phase and the transfer of dissolved AP to the latter is shown. The orders of the salting-out effect of the different cations and anions with respect to alkylphenol have been ascertained.
