| 摘 要： | 研究了十六烷基三甲基溴化铵（CTMAB）-硫氰酸钾-水体系浮选分离钛的行为。结果表明, 在水溶液中, Ti与CTMAB和硫氰酸钾形成不溶于水的三元缔合物［Ti(SCN)62- ］［CTMAB+］2，此三元缔合物沉淀浮于水相上层形成界面清晰的液-固两相。当溶液中CTMAB和硫氰酸钾的浓度分别为2.0×10-3mol/L和7.0×10-2mol/L时, Ti可与CdⅡ、Cr、MnⅡ、V、Al、NiⅡ、FeⅡ、MgⅡ和Ga离子定量分离。该方法简便迅速，不污染环境,在微量钛的分离和富集分析中有很好的实用价值。

| Abstract: | The floatation separation behavior of titanium in cetyl trimethyl ammonium bromide (CTMAB)-potassium thiocyanate-water system was studied. The results showed that a water-insoluble ternary complex (［Ti(SCN)62-］［CTMAB+］2) was formed by Ti , CTMAB and potassium thiocyanate in water solution. This complex could float on water phase, generating liquid-solid phases with clear interface. When the concentration of CTMAB and potassium thiocyanate was 2.0×10-3 mol/L and 7.0×10-2 mol/L, respectively, Ti could be quantitatively separated from Cd Ⅱ, Cr , Mn Ⅱ, V , Al , Ni Ⅱ, Fe Ⅱ, Mg Ⅱ and Ga . The proposed method was simple and rapid without environmental pollution. It had good practical value in separation and enrichment analysis of trace titanium. |
