1-苯基-3-甲基-4-三氟乙酰基吡唑酮-5(PMTFP)与磷酸三丁酯(TBP)或三正辛基氧化膦(TOPO)对三价稀土的协同萃取已有报道。本文研究了1-苯基-3-甲基-4-二氯乙酰基吡唑酮-5(PMDCP)和TOPO的氯仿溶液从硝酸介质中对La~(3+)、Nd~(3+)、Dy~(3+)和Yb~(3+)的协同萃取。 试验时将有机相与含硝酸稀土的水溶液共置于分液漏斗中,在一定温度下萃取30分钟。
Synergistic Extraction of Trivalent Rare Earth with 1-Phenyl-3-methyl-4-trifluoroacetylpyrazolone-5 (PMTFP) and Tributyl Phosphate (TBP) or Trioctylphosphine Oxide (TOPO) There are reports. In this paper, the effects of 1-phenyl-3-methyl-4-dichloroacetylpyrazolone-5 (PMDCP) and TOPO in chloroform on the growth of La 3+, Nd 3+, , Dy ~ (3+) and Yb ~ (3+). During the experiment, the organic phase was co-placed in a separatory funnel with an aqueous solution of rare earth nitrate and extracted for 30 minutes at a certain temperature.
