近年来国内外对1-苯基-3-甲基-4-苯甲酰基-吡唑酮-5(即HPMBP)萃取稀土的行为作了不少的工作。Roy等曾研究了HPMBP对15个稀土离子的萃取,测得萃合物的组成为REA_3。刘建民等测得的萃合物组成为REA_3·HA,并制备出相应组成的固体络合物。黎乐
In recent years, many studies have been done on the behavior of rare earths extracted by 1-phenyl-3-methyl-4-benzoyl-pyrazolone-5 (HPMBP) Roy et al. Studied the extraction of 15 rare earth ions by HPMBP and determined the composition of the extract as REA_3. Liu Jianmin measured the composition of the composition of REA_3 · HA, and prepared the corresponding composition of the solid complex. Li Le
