STUDY OF THE SEPARATION OF MICROTUNGSTEN (Ⅵ) BY P_(350) EXTRACTION CHROMATOGRARHY

Zhang Zhongxin Jiang Yu (Department of Chemistry) Wang Chi (The Centre of Physics and Chemistry)  
In this paper,we have proposed a new method for the separation of w by extraction chromatography with P_(350) as stationary phase,silicagel as supporter,3.0mol/L HCL—1.0 mol/L MgCl_2—1% Tar as fluid phase.we studied the conditions for separating and eluting,and disturbance factors,etc.under the given experimental conditions,W can be alternatively and quantitatively separated from Mo and Ti.By spectrophotometric determination of W with Salicylicylfluorone and Cetyltrimethyl-Ammonium Bromide, micro-W is separated and determined with good results in several kinds of allo(?) steel and ore.
