利用阳离子表面活性剂的胶束分光光度法是提高钨灵敏度的有效手段。目前,在盐酸介质中采用水杨基荧光酮与溴化十六烷基三甲基铵测定钨取得较好的结果。本法是水相介质中分光光度法测定钨灵敏度最高的方法之一。
Micellar spectrophotometry using cationic surfactants is an effective method to increase the sensitivity of tungsten. At present, the use of salicylfluorone and cetyltrimethylammonium bromide in the determination of tungsten in the hydrochloric acid medium gives better results. This method is one of the most sensitive methods for the determination of tungsten by spectrophotometry in aqueous medium.
