The composition of the synergistic adduct has been determined to be M(PA)3·2TBPO (M=Ce(III), Eu(III), Tm(III)). The effect of various anions and cations on the extraction of these metal ions has also been studied. Among the anions, fluoride, oxalate, citrate and cyanide ions masked the extraction, whereas Fe(III) and Cu(II) reduced the extraction to ∼90%. The formation constant, and separation factor from various metal ions has also been determined and discussed. © 2004 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/12/2004(2004-12-01), 925-929 0033-8230 92:12/2004<925 2004 92 ract https://doi.org/10.1524/ract.92.12.925.55102 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/ract.92.12.925.55102 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Ali Akbar NATIONALLICENCE 773 0- Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/12/2004(2004-12-01), 925-929 0033-8230 92:12/2004<925 2004 92 ract CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
