摘　　要：在乙醇 水混合溶液中 ,1 苯基 3 甲基 4 苯甲酰基吡唑酮 5与Nd(Ⅲ ) ,Eu(Ⅲ ) ,Ho(Ⅲ )等及乙醇形成了萃合物 ,使萃取分配比明显提高。利用斜率法研究了萃取机理。借助红外 (IR)、元素分析、热分析 (TG DTA)In C 2H 5OH H 2O solution, 1 phenyl 3 methyl 4 benzoylpyrazolyltone 5 was combined with rare earth ions RE(Ⅲ) (RE=Nd, Eu, Ho) and ethynol to form an complex, and the complex was extracted into a CHCl 3 phase. The extraction mechanism was studied with the solpe method and the complex was characterized by means of IR, elementary analysis, and thermal analysis.
