研究了用Na2 WO4 溶液进行钨的离子交换时 ,溶液中SO2 - 4、Cl- 、OH- 的存在对钨交换容量的影响 ,试验表明 ,随着上述三种阴离子浓度的增加 ,钨的交换容量明显降低。同时 ,三种阴离子存在时的正交试验表明 ,其对钨的交换容量影响程度的顺序为 :Cl- >SO2 - 4>OH- ,交前液中 [WO3]=2 0g/L ,[SO2 - 4]<0 0 312 5mol/L ,[Cl- ]<0 0 0 84 6mol/L ,[OH- ]<0 4 70 6mol/L是可行的。在上述阴离子存在下 ,通过串柱离子交换可提高钨的交换容量。 The effect of SO2 - 4, Cl - and OH - on the exchange capacity of tungsten was studied in the case of ion exchange of tungsten with Na2 WO4 solution. The results showed that with the increase of the concentration of the three anions, the exchange capacity of tungsten Obvious reduction. In the meantime, the orthogonal experiments of the three anions show that the order of influence on the exchange capacity of tungsten is Cl-> SO2-4> OH-, [WO3] = 20g / L, [SO2 - 4] <0 0 312 5mol / L, [Cl-] <0 0 0 84 6mol / L, [OH-] <0 4 70 6mol / L is feasible. In the presence of the above anions, the exchange capacity of tungsten can be increased by string ion exchange.
