摘要
用三氯化钛将钨还原为五价,在盐酸溶液中,钨(V)与硫氰酸离子生成黄绿色络合物,选择用723pc分光光度计测定。此方法具有速度快,操作简便,误差小等优点。
The tungsten is reduced to pentavalent with titanium trichloride, in hydrochloric acid solution, tungsten （V） and thiocyanate ions generate yellow-green complex, selected with 723pc spectrophotometer determination. This method has the advantages of fast speed, simple operation and small error.
