Abstract
The extraction behavior of Al(III), Ga(III) and In(III) was investigated using bis(1,1,3,3-tetramethylbutyl)phosphinic acid (MBP) and its sulfur analogues, bis(1,1,3,3-tetramethylbutyl)monothiophosphinic acid (MTP) and bis(1,1,3,3-tetra-methylbutyl)dithiophosphinic acid (DTP) as extradants. A typical chelate extraction behavior was observed in these extraction systems in the pH range examined. The degree of extraction was in the order of In(HI)>Ga(III)>Al(III). Moreover, the ability of extractants for mutual separation of these metals from one another decreased in the following order: DTP>MTP>MBP. The quantitative mutual separation of these metals can be achieved using DTP/hexane with single extraction. In the higher HC1 concentration range, however, slight extraction of Ga(III) and In(HI) was observed; this is due to the extraction of GaCl4− and InCl−4 pairing with the protonated extractants.
