摘要: 酸性磷(瞵)酸酯是一类重要的萃取剂,它们对金属离子的萃取性能和机理研究巳有报导,但大多限于溶液体系[1-3]。酸性磷酸酯金属萃合物的研究也有报导[4,5],但对固态烷基膦酸单烷基酯金属萃合物方面的报导较少。本文报导2-乙基已基膦酸2-乙基已基酯(简称HEH(EH)P或HA)金属(M=Co、Ni、Cu、Zn)固体萃合物的磁性,电子光谱和红外光谱,结合热分析结果对萃合物的成键特性和可能构型进行了讨论。

Abstract: The solid complexes were formed in the extraction of divalent metals (Co,Ni,Cu,Zn)from their nitrate solutions by 2-ethylhexyl phosphonic acid mono (2-ethlyhexyl) ester (HEH(EH)P). These complexes have been examined by elemental analysis, magnetic moment measurement and thermal analysis. The infrared spectra bave been investigated for HEH(EH)P-M(Ⅱ)(M=Co,Ni,Cu,Zn). The structures of the complexes have been elucidated.

Key words: Solvent extraction, 2-ethylhexyl phosphonic acid 2-ethylhexyl ester, CO,Ni,Cu,Zn ions, Solid complex
