摘要: 本文研究了硫酸根阴离子对1-苯基-3-甲基-4-苯甲酰基吡唑酮-5(HPMBP,HL)及三辛胺(TOA)协同萃取镨(Ⅲ)及钕(Ⅲ)的影响。发现在SO42-体系中协萃机理为: ![]() c="http://www.rhhz.net/qikantupian/WJHXXB-19900116-89-2.gif" /> 式中Ln3+=Pr3+或Nd3+,下标“o”指示有机相中物种,无下标指示水相中物种。固体萃合物的红外光谱及元素分析数据确证了上述机理。 |

Abstract: The extraction of Pr(Ⅲ) and Nd(Ⅲ). from sulfate medium with 1-pheny1-3-methyl-4-benzoy1-pyrarol-5-one(HPMBP,HL) and tri-n-octylammonium salt (HTOA+HSO42-,BX) in toluene was investigated. The mechanism of synergic extraction was found to be ![]() c="http://www.rhhz.net/qikantupian/WJHXXB-19900116-89-2.gif" /> where Ln=Pr or Nd; subscript' o' denotes species in the organic phase,while lack of any subscript denotes species in the aqueous phase.IR spectra and elemental analysis of solid extracted complex of Nd (Ⅲ) were also studied. The results confirmed the extraction mechanism.Like extraction from Cl- medium the antagonistic effect was also observed in the region of higher concentration of HTOAHSO4. |
