| Abstract: H2A is one of a series of bis acyl pyrazolone chelate extractants synthesized recently. In this paper,the complexation and the extraction behaviour of H2A with eleven rare earth ions,thorium(Ⅳ) and uranium (Ⅵ) have been studied in nitric acid. Experimental results showed that the composition of the extracted compounds are LnA·HA,ThA2and UO2A,respectively,in the same experimental condition. Their pH1/2 was determined. Their extractive constants log Ksx were calculated by the slope method. The solid complexes of several rare earth ions were produced. Their composition of these complexes was characterized by elemental analysis,UV,IR and TG-DTA studies. |
