Ekberg, J-O. Liljenzin, M. Nilsson, G. Skarnemark] The separation of actinides and lanthanides is an important question in the treatment of spent nuclear fuel in the transmutation concept. To find an efficient and well functioning separation process it is necessary to study the chemistry of the elements in the two groups in different aqueous media. The stability constants of the nitrate complex formation with Pm, Eu, Am and Cm were determined using solvent extraction. The extraction was studied using the synergistic system of 2,6-bis-(benzoxazolyl)-4-dodecyloxylpyridine and 2-bromodecanoic acid in tert-butyl benzene. As the nitrate ion concentration in the aqueous phase was increased, a decrease in separation between actinides and lanthanides was seen owing to complex formation between the different elements and the nitrate ions. © 2004 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Andersson Sofie aut Ekberg C. aut Liljenzin J-O aut Nilsson M. aut Skarnemark G. aut Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/12/2004(2004-12-01), 863-867 0033-8230 92:12/2004<863 2004 92 ract https://doi.org/10.1524/ract.92.12.863.55109 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/ract.92.12.863.55109 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Andersson Sofie aut NATIONALLICENCE 700 1- Ekberg C. aut NATIONALLICENCE 700 1- Liljenzin J-O aut NATIONALLICENCE 700 1- Nilsson M. aut NATIONALLICENCE 700 1- Skarnemark G. aut NATIONALLICENCE 773 0- Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/12/2004(2004-12-01), 863-867 0033-8230 92:12/2004<863 2004 92 ract CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
