Abstract

The extraction of Mg(II), Ca(II), Sr(II), Ba(II), Mn(II), Co(II), Ni(II), Cu(II), Eu(III) and Am(III) from mineral acid solutions with triethylene glycol bis(dodecyl phosphate) (<strong>H<sub>2</sub>A</strong> = HO(H<sub>25</sub>C<sub>12</sub>O)P(O)(OCH<sub>2</sub>CH<sub>2</sub>)<sub>3</sub>OP(O)(OC<sub>12</sub>H<sub>25</sub>)OH) in different diluents was investigated. The formation of complexes was followed by NMR spectrometry; their composition in the organic phase was determined by slope analysis and proved by MALDI-TOF mass spectrometry. M<sup>II</sup>(HA)<sub>2</sub> and M<sup>III</sup>(HA)A species are formed in the organic phase while M<sup>z+</sup>(H<sub>2<i>m</i>-<i>z</sub></i>A<i><sub>m</sub></i><sup>z-</sup>)· <i>n</i>OcOH species (<i>m</i> = 2 or 3; <i>n</i> = 0, 1, 2; <i>z</i> = 2 or 3) in (octan-1-ol)-containing diluents. <p>
