Yf. Sun et Ba. Moyer, PHASE VOLUME CHANGES ACCOMPANYING WATER EXTRACTION FROM AQUEOUS-ELECTROLYTE SOLUTIONS BY 1-OCTANOL, Solvent extraction and ion exchange, 13(2), 1995, pp. 243-252
The extraction of water by I-octanol was calculated as a function of a
queous electrolyte concentration and initial O/A volume ratio for seri
es of representative salts, including LiCl, NaCl, KCl, NaNO3, NaClO4,
MgCl2, and CaCl2, These results were then used to calculate the result
ant phase-volume changes and aqueous-electrolyte-concentration changes
. Such corrections are necessitated for precise extraction measurement
s employing 1-octanol as a diluent, especially as the O/A phase ratio
exceeds unity.
