| Abstract: | A method for the determination of Mn in cast iron of high-content Cr by flame atomic absorption spectrometry was reported. SrCl_2 was used as the releasing agent to eliminate the interference of Si.The sample was dissolved in hydrochloric acid, and perchloric acid was added to decompose the carbide of Cr and Mn.Satisfactory results were obtained for the determination of Mn in cast iron of high-content Cr. |
