【Abstract】 In this paper, the possibility of simultaneous determination of tungsten and molybdenum in the system of W ( Mo ) -PF-CTMAB has been studied. The experimental conditions were optimized by simplex method and simultaneous determination of W and Mo was carried out by factor analysis spectrop-hotometry. The results showed that it increased the sensitivity and expanded the detection range and improved the stability of the complex system, it has been successfully applied to the analysis of W and Mo in steels and the results obtained are satisfactory.更多还原
