Abstract：The test solution was prepared by phosphoric acid and perchloric acid dissolution method, then to take same solution, the photometric method and titration method were respectively used to determine the contents of W, Mn, Mo, Co, Cu, V and Cr elements. By controlling the acidity during determination, the linear of each element was good. The method has shortened the cycle, high precision and accuracy of the analysis. RSD of W, Mn, Mo, Co, Cu, V and Cr were separately less than or equal to 1.42%, 1.26%, 2.12%, 6.72%, 5.73%, 3.53%, 1.53%, being able to meet the requirements of rapid determination.
