Chemical Equilibrium and Synergism for Solvent Extraction of Trace Lithium with Thenoyltrifluoroacetone in the Presence of Trioctylphosphine Oxide
Equilibria and applications of a synergistic extraction were studied for the determination of a trace lithium by using thenoyltrifluoroacetone (TTA) and trioctylphosphine oxide (TOPO) as ligands. Several equations were derived for the extraction of lithium into m-xylene as a phase of Li-TTA·mTOPO adduct. Distribution coefficients and extraction constant were determined together with a stability...
متن کاملSelective and Efficient Solvent Extraction of Copper(II) Ions from Chloride Solutions by Oxime Extractants
Oxime extractants 3-tert-butyl-2-hydroxy-5-methyl benzaldehyde oxime (HL1) and 3-tert-butyl-2-hydroxy-5-methoxy benzaldehyde oxime (HL2) were synthesized and characterized by conventional spectroscopic methods. Suitable lipophilic nature of the prepared extractants allowed examining the ability of these molecules for extr...

The extraction of Gadolinium (Gd) from perchlorate and nitrate media in 1,2-dichloroethane(C2H4Cl2), carbon tetrachloride (CCl4) and chloroform (CHCl3) by mixtures of 2-thenoyltrifluoroacetone (HTTA) and a crown ether benzo-15-crown-5 (B15C5) is investigated.The composition of the extracted species is determined as Gd(TTA)3.nB15C5 (n=1 in nitratemedium and n=2 in perchlorate medium). The values...
