Mutual separation of indium(III), gallium(III) and zinc(II) with alkylated aminophosphonic acids with different basicities of amine moiety
文摘
•

α-Aminophosphonic acid extractants (α-APA) with different amine basicities were newly prepared as selective extractants for In(III) and Ga(III).

•

(α-APA) with the amine moiety of higher basicity exhibited higher selectivity for In(III), Ga(III) and Zn(II).

•

The extraction equilibria for Ga(III) and Zn(II) with (α-APA) were determined.
