Nuclear and radiochemical techniques in chemical analysis. Progress report, August 1, 1978-July 31, 1979
Studies of homogeneous liquid-liquid extraction have been extended to include (1) a detailed determination of the phase diagram of the system propylene carbonate-water, (2) the extraction of a large variety of both monodentate and bidentate iron complexes, (3) the solvent extraction characteristics...

Subsequent evaporation of the ethanol restores the two immiscible phases.
