Solubilization of a calixarene carboxylic acid derivative in an aliphatic organic solvent was accomplished by utilizing a reverse micellar solution. The reverse micellar solution was prepared by cationic cetyltrimethyl ammonium bromide (CTAB) or anionic bis-2-ethylhexyl sulfosuccinate (AOT). Both reverse micellar solutions facilitate the solubilization of the calixarene carboxylic acid derivative in isooctane. The concentration of calixarene solubilized in the reverse micelles increases with an increase of surfactant concentration. The water content in the reverse micelles (W0 = [H2O]/[surfactant]) also affects the solubilization behavior of calixarene. The optimum water content existed for the formation of the reverse micelles and the value was around 20. The extraction performance of calixarene solubilized was investigated for yttrium (III) in isooctane. The extraction ability of calixarene was enhanced by solubilizing in the anionic reverse micellar solution.
