- •
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.
