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SO_4~(2-)体系中协萃机理为:(LnL_3)_o+(HTOAL)_o(HTOA~+LuL_4~-)_o及(HLnL_4)_o+(TOA)_o(HTOA~+LnL_4~-)_o式中Ln~(3+)=Pr~(3+),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。
In this paper, the synergistic extraction of praseodymium (Ⅲ) and neodymium (Ⅲ) from 1-phenyl-3-methyl-4-benzoylpyrazolone-5 (HPMBP, HL) and trioctylamine (TOA) Impact. It is found that the mechanism of extraction in SO_4 ~ (2-) system is: (LnL_3) _o + (HTOAL) _o (HTOA ~ + LuL_4 ~ -) _o and (HLnL_4) _o + (TOA) _o (HTOA ~ + LnL_4 ~) _o Where Ln ~ (3 +) = Pr ~ (3 +), the subscript “o” indicates the species in the organic phase, no subscript indicates the species in the water phase. Infrared spectra of solid extracts and elemental analysis data confirm the above mechanism.
