异丙基膦酸单(1-己基-4-乙基)辛酯与HPMBP协同萃取稀土元素(Ⅲ)
摘要:
异丙基麟酸单(1-己基-4-乙基)辛酷(PT-2,HL)是结构类似于2-乙基己基麟酸单2-乙基己基酷(HEH/EHP)的烷基麟酸单烷基酚,它对稀土元素的萃取已有研究[1].

Synergisitic Extraction of Rare Earth(Ⅲ) by PT-2 and HPMBP
Abstract:
The synergistic extraction of rare earth(Ⅲ) including La, Nd,Y,Gd,Yb from aqueous mineral acid solution (H2SO4,HCl, HNO3) by isopropyl phosphonic acid mono(1-hexyl-4-ethyl) octyl ester (PT-2, HL) with 1-phenyl-3-methyl-4-benzoyl-pyrazolone-5 (HPMBP, HA) in benzeiie has been investigated. The compositions of the synergistic ex-tracted complexes and the equilibrium constants were determined and calculated respectively. The relationship between structures of the extractants and synergistic effects has been discussed. The mechanism of the synergistic extraction has been discussed also.
