摘要: 本文叙述了N,N-二乙胺甲酰甲撑膦酸二己酯(DHDECMP)从硝酸介质中萃取钆的各种影响因素;推出了萃合物的组成Gd(NO_3))_3·3 DHDECMP和萃取反应热△H=-22.1 kJ/mol;对反萃条件作了探讨。Abstract: In this paper factors influencing the extraction of Gd with DHDECMP inHNO_3 medium is studied. The composition of the complex extracted is found tobe Gd(NO_3)_3. 3DHDECMP and the heat of extraction is found to be △H=-22.1kJ/mol. The optimum conditions for extraction are reported.
