Description 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)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- n OcOH species, m = 2 or 3 ( n = 0, 1, 2) (z = 2 or 3) in n-octan-1-ol -containing diluents.
