丙醇水溶液在氯化钠的作用下可分成醇-水两相,在分相过程中,GaCl4-与罗丹明B( RhB)生成的[GaCl4-][RhB+]能被丙醇相完全萃取.当溶液中丙醇和罗丹明 B 的浓度分别为30%(v/v),0.3 g/L 时, Ga(Ⅲ)的萃取率达到97.8%以上,而Zn(Ⅱ)、Al(Ⅲ)、Ir(Ⅳ)、Rh(Ⅲ)、V(Ⅴ)和Ti(Ⅳ)基本不被萃取,实现了Ga(Ⅲ)与上述金属离子的分离.

The results showed that the 1-propanol-water solution could be well divided into two phases at the pres-ent of sodium chloride. The associated [ GaCl4-] [ RhB+] formed from GaCl4- and rhodamine B could be completely extracted during this process. Ga(Ⅲ) could be quantitatively separated from Zn(Ⅱ), Al(Ⅲ), Ir(Ⅳ), Rh(Ⅲ), V(Ⅴ) and Ti(Ⅳ) by extraction, and the extraction percentage of Ga(Ⅲ) was over 97. 8% when the concentrations of 1-propanol and Rhodamine B in solution were 30% (v/v) and 0. 30 g/L, respectively.
