摘要
研究了硫酸铵-乙醇-铬天青S体系萃取分离和富集铝的行为及与一些金属离子分离的条件。硫酸铵能使乙醇的水溶液分成两相,在分相过程中,Al3+和铬天青S(CAS)生成的Al(CAS)2-能被乙醇相完全萃取,Pb2+、Pd2+、Cr3+、Ru3+、Ir4+、Ni2+、Mg2+、Co2+和Fe2+不被萃取而和Al3+分离。
The behavior and conditions of extraction separation of aluminum from other metal ions in （NH4 ）/S04-ethanol-chrome azurol S system were studied. The results showed that the ethanol -water solution could be well divided into two phases in the presence of （NH4 ）2SO4. The AI（CAS） 2 - （combined from Al3 ＋ and chrome azurol S） could be completely extracted during this process. Al3 ＋ could be quantiatively separated from Pb2 ＋ , Pd2 ＋ , Cr3 ＋ , Ru3 ＋ , Ir4＋ , Ni2＋, Mg2 ＋ , Co2 ＋ and Fe2 ＋ by extraction.
