锡与钼、镓、铈和钨的绿色析相萃取富集和分离研究

Studies on Green Extraction and Enrichment Separated of Sn from Mo, Ga, Ce and W by Phase Separation

    摘要
  • 摘要: 在硫酸铵存在下,乙醇水溶液能够分为醇/水两相,在分相过程中,C2H5OH+2与Sn(SCN)5~6 (5~6)-4-生成的C2H5OH21~2Sn(SCN)5~6三元缔合物能被乙醇相萃取,使Sn(Ⅳ)与Mo(Ⅵ)、Ga(Ⅲ)、Ce(Ⅲ)和W(Ⅵ)离子分离.该方法在微量锡的分离和富集分析中有一定的实用价值

     

    Abstract: The ethanol aqueous solution could be well divided into two phases of ethanol/water under the effect of ammonium sulphate. The associated ［C2H5OH2］1~2［Sn(SCN)5~6］ formed from C2H5OH+2 and ［Sn(SCN)5~6］［(5~6)-4］- could be extracted during this process. Sn(Ⅳ) could be separated from Mo(Ⅵ), Ga(Ⅲ), Ce(Ⅲ) and W(Ⅵ) by extraction. This method is practical to the separation and enrichment of trace stannum
