【Abstract】 The catalytic polarographic behaviour of molybdenum in the presence of large amount of tung sten has been investigated. Optimun conditionus for the determination of molybdenum in pure tungsten, and the application to the analysis of pure yellow tungstic acid and sodium tungstate are established. No preliminary separation is necessary, and the molybdenum content can be determined directly. The dection limit is 1 ppb. The relative standard deviation is smaller than 10%.更多还原
