【摘要】用1-苯基-3-甲基-4-苯甲酰基-5-吡唑啉酮（PMBP）做萃取剂研究了从HNO₃介质中痕量钪的溶剂萃取行为。发现在很低的酸度下,PMBP几乎可以定量地萃取痕量的钪。同时,也讨论了用PMBP从¹⁸O离子辐照过的铀靶溶液中萃取分离钍时钪的沾污。更多还原

【Abstract】 The solvent extraction behavior of the trace Sc was studied from nitric acid media with 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone (PMBP) as an extractant. It was found that the trace Sc can be extracted quantitatively into the organic phase from dilute nitric acid solutions. At the same time the contamination of the trace Sc in the thorium fraction separated from the solution of the uranium targets though PMBP extraction was discussed.更多还原
