摘要
研究了新型双β二酮萃取剂,2,6双[(1苯基3甲基5氧4吡唑啉基)甲酰基吡啶(PDCBP,简称H2A)的氯仿溶液对铜的萃取行为,所得萃合物组成为Cu(HA)2,计算了有关萃取热力学函数,测定了H2A对Cu2+、RE3+、Th(Ⅳ)、Zr(Ⅳ)、Hf(Ⅳ)等元素的分离因子,并与类似试剂作了比较.
In this paper,the extraction behavior of cupric ion with 2,6biscarbobyl (1phenyl3methyl5oxopyrazolingl)]pyridine (H 2A)has been investigated.The compostion of the extracted complexe is Cu(HA) 2.The separation factors of Cu 2+ to other twelve elements have been compared.
