1－苯基－3－甲基－4－（α－呋喃甲酰基）－5－吡唑酮对稀土（Ⅲ）钍（Ⅳ）和铀（Ⅳ）的萃取行为研究

Study on The Extraction Behaviors of Rare Earth Ions(Ⅲ) ,Thorium (Ⅳ)and Uranium (Ⅵ) with 1-Pheny1-3-Methy1-4-(α- Furoyl )-5-Pyrazolone

研究了题示试剂（ＨＡ）萃取稀土（Ⅲ）、钍（Ⅳ）和铀（Ⅵ）的行为，研究了萃取机理，确定了萃合物的组成，求得了萃取平衡常数，并制备了稀土的固态萃合物，对其组成、ＩＲ、ＵＶ、ＴＧ和ＤＴＡ进行了表征。

The extraction behaviors of RE(Ⅲ) [except Nd(Ⅲ)and Pm(Ⅲ)],Th(Ⅳ)and U(Ⅵ)with 1-Pheny1-3-Methy1-4-(α- Furoyl ) - 5 - Pyrazolone are described in the paper.The extraction equlibrium constants were calculated.And the formulas of the extracted complexes were shown respectively.The solid compleses of some RE( Ⅲ ) were prepared and their compositions were characterized by elemental analysis,IR ,UV,TG and DTA.
