The Research on CPB Extracting Bi(Ⅲ) with the Dual Water Phase System
Author(s): 
Pages: 57-58
Year: Issue:  4
Journal: JOURNAL OF JIAOZUO UNIVERSITY

Keyword:  溴化十六烷基吡啶(CPB)乙醇萃取分离铋离子;
Abstract: 文章研究了在硫酸铵存在下,乙醇与水能够分为醇/水两相,在分相过程中,Bi(Ⅲ)与I-及CPB+缔合生成BiI3-6(CPB+)3,该三元缔合物能够很好地被乙醇相萃取.通过控制pH值,能够使Bi(Ⅲ)与Mn(Ⅱ)、Fe(Ⅲ)、Co(Ⅱ)、Ni(Ⅱ)、Zn(Ⅱ)、Al(Ⅲ)等常见离子完全分离.
