摘要: 通过固态萃合物2-乙基己基膦酸单(2-乙基己基)酯(HEH(EH)P,HA)-Mn的制备,对单烷基膦酸酯萃取二价Mn离子的萃合物组成及萃取机理进行了研究。结果表明:萃合物为不含水分子,组成为MnA_2,属高旋弱场配合物;认为萃合物为四面体结构。

Abstract:In order to clarify the mechanism and the complex formed in the ex-traction of divalent Mn by alkylphosphonic acid monoester, the solid complex hasbeen prepared by mono (2-ethylhexyl)-2-ethylhexyl phosphate, HEH(EH)P, HA withdivalent Mn. The elemental analysis, magnetic susceptibility and thermogravimetryhave been determined for the solid complex of HEH(EH)P-Mn(Ⅱ) and the infraredspectrum has been carried out in comparison to the extractant HEH(EH)P. The extra-cted compound has also been studied by electronic and electron spin resonance spec-troscopy in octane solvent and solid state at room temperature. On the basis of themeasurements, it is concluded that the structure of the solid polymeric species MnA_2is in a tetrahedral arrangement.
