Spectrophotometric study of copper(II), aluminum(III), iron(III) and uranim(VI) complexes of 2-thenoyltrifluoroacetone(TTA) in aqueous solution containing nonaoxyethylene dodecyl ether(BL-9EX) is described. For copper(II) and uranium(VI) systems, the metal-TTA-Trioctylphosphine (TOPO) mixed complexes have been studied. The molar absorptivities of the copper(II)-, aluminum(III)-, iron(III)- and uranium(VI)-TTA complexes were 3.62×10^4 (at 342 nm), 7.68×10^4 (at 348 nm), 4.40×10^4 (at 388 nm) and 2.58×10^4 (at 383 nm), respectivily. The composition of these metal-TTA and metal-TTA-TOPO complexes has been determined and the equilibrium constants for these complexes were obtained.
