Sažetak

Extraction of cadmium(II) from aqueous acetate buffered media with benzoyltrifluoroacetone (BTA) in benzene has been studied with and without the addition of auxiliary ligands like pyridine (PY), 3-methylpyridine (3MP), 4-methylpyridine (4MP), pyridine N-oxide (PO), 2-methylpyridine N-oxide (2MPO), 4-methylpyridine N-oxide (4MPO), tributylphosphate (TBP) and trioctylphosphine oxide (TOPO). Synergistic enhancement was observed in all systems. Extraction constants and adduct forma ti on constants have been calculated. Adduct formation constants increase in the following order.
