| 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C2H5OH2]1~2Sn(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 ~ 2Sn( SCN)5 ~ 6] formed from C2H5OH+2and 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. |
