Extraction of several metals from chloride salt solutions with heptafluorodimethyloctanedione

Distribution coefficients for 17 metals between aqueous chloride salt solutions and 1,1,1,2,2,3,3-heptafluoro-7,7-dimethyl-4,6-octanedione-tri- octylphosphine oxide solutions in dodecane were determined in the pH range 2-12. Loading isotherms, distribution coefficient dependence on extractant concen...

Zusammenfassung:	Distribution coefficients for 17 metals between aqueous chloride salt solutions and 1,1,1,2,2,3,3-heptafluoro-7,7-dimethyl-4,6-octanedione-tri- octylphosphine oxide solutions in dodecane were determined in the pH range 2-12. Loading isotherms, distribution coefficient dependence on extractant concentration, and synergistic effects of extractant mixtures vs. the individual components are shown for several metals, representative of their periodic class.
