硫脲树脂分离钼、钨的研究

Study on separation of tungsten and molybdenum with sulfourea resin

研究了硫脲树脂对钼、钨的吸附行为，提出了分离钼、钨的条件，可用于实际样品中钼、钨的分离，回收率达９５％以上。

A chromatographic method was proposed for the separation of Mo and W by using sulfourea resin.The adsorption and separating factor were also studied.After eluting coexisting ions with 0 02 mol/L HCl,W and Mo were separated by elution with 1 5 mol/L HCl 0 01 mol/L H 2C 2O 4 and 2 0 mol/L HCl.The method has been used to separate Mo and W in steel samples,the results are satisfactory.
