摘要: 酸性磷酸酯金属配合物组成和结构的测定有利于阐明萃取机理,是萃取化学中令人感兴趣的课题。标题配合物由于热稳定性差、挥发性小而且分子量大[1](结构筒式I,简称LnL3),常规的质谱分析(EIMS、CIMS)难以进行。本文应用FABMS成功地对此配合物作了测定,并用亚稳跃迁技术对其裂解规律进行了探讨。

Abstract: Fast atom bombardment (FAB) mass spectra of lanthanide complexes of 2-ethythexylphosphonic acid mono-2-ethylhexyl ester (LnL3, Ln = La, Pr, Nd, Eu, Dy, Ho, Lu) werereported.The quasi-molecular ions [LnL3·H]+ and a series of ion species [LnL3·(HL)n ·H]+(n = 1,2,3) are shown in FAB mass spectra.The mechanism of formation of the ionspecies are discussed.FAB, linked scanning techniques were applied in this work.
