PHASE VOLUME CHANGES ACCOMPANYING WATER EXTRACTION FROM AQUEOUS ELECTROLYTE SOLUTIONS BY 1-OCTANOL

ABSTRACT

The extraction of water by 1-octanol was calculated as a function of aqueous electrolyte concentration and initial O/ volume ratio for a series of representative salts, including LiC1, NaC1, KC1, NaNO₃, NaCIO₄, MgCl₂, and CaCl₂ These results were then used to calculate the resultant phase-volume changes and aqueous-electrolyte-concentration changes. Such corrections are necessitated for precise extraction measurements employing 1-octanol as a diluent, especially as the O/A phase ratio exceeds unity.
