摘要：

Gallium(III) and indium(III) extractions from aqueous thiocyanate media by trilaurylamine (TLA) in toluene have been studied. The extracted species are most probably In(NCS)3(HTLASCN)3, Ga(NCS)3(HTLASCN) and Ga(NCS)3(HTLASCN)2. Though the presence of cationic Ga(NCS)n(3-n)+ species (0 < n < 3) in aqueous phase is sufficient to explain the gallium extraction, the presence of anionic In(NCS)n(n-3)- species (n > 3) is also necessary to explain the indium one. Ga, In and Al elements can be separated using this extraction system. © 1979.
