| Abstract: | Niobium and its compounds have many uses in metallurgical, electrical,communication and a lot of high technical fields. It is necessary to set up a fast and correct analytical method, which should be suited to the requirements of products. Under normal conditions, we have to use several testing methods to determine impurity elements in niobium. It took us a tedious analytical time. On the basis of studying niobium spectral lines, we develop the analytical method of determining impurity elements Al, Cr,Cu,Fe, Mo, Ni, Pb,Si, Ta,Ti, W, Zr in high purity niobium by high-resolution sequential ICP spectrometer. |
