本研究了以P_(350)为固定相,硅胶为载体,以3.0mol/L HCl—1.0mol/L MgCl_2—1％Tar 混合溶液为流动相的萃取色谱法分离钨(VI)的新方法,考察探讨了分离条件、洗脱条件和共存离子干扰等。在拟定的实验条件下,钨可以有效的和 Mo(VI)、Ti(IV)分离,结合水杨基萤光-酮溴化十六烷基三甲基铵分光光度法,应用于多种合金钢和矿物中微量钨的分离与测定,结果良好。
In this paper, a new method for the separation of tungsten (VI) by extraction chromatography with P_ (350) as stationary phase and silica gel as mobile phase with 3.0mol / L HCl-1.0mol / L MgCl_2-1% Tar mixed solution as mobile phase, Investigated the separation conditions, elution conditions and coexistence of ion interference. Under the experimental conditions, tungsten can be effectively separated from Mo (VI) and Ti (IV), and combined with salicyl fluorophone-cetyltrimethylammonium bromide bromide spectrophotometry, it can be used in many kinds of alloy steel and Trace minerals in the separation and determination of tungsten, the results are good.
