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) (H2A = HO(H25C12O)P(O)(OCH2CH2)3OP(O)(OC12H25)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. MII(HA)2 and MIII(HA)A species are formed in the organic phase while Mz+(H2m-zAmz-)· nOcOH species (m = 2 or 3; n = 0, 1, 2; z = 2 or 3) in (octan-1-ol)-containing diluents.
