| Abstract: | Aim To resolve the problems of long period, complex operation and many steps when determining impure elements in ferrosilicon by classic methods. Methods A method was tried to study for determination of four impure elements, Al, P, Ca, Mn at the same time by Inductively Coupled Plasma Atomic Emission Spectrometry. The sample was dissolved only once time. Results The recommended method is shown satisfying precision and acuracy, the relative standard deviation is less than 2.8%. Conclusion The method is proved to be simple and rapid, which can replace the classical chemical one. |
