| Abstract: | In the system of high valence chromium and manganese the effect of selective reduction of mercurous nitrate on the manganese has been studied On this basis a new method for simultaneous spectrophotometric determination of chromium and manganese in stainless steel by the reduction has been developed The other compositions of stainless steel has not any interference on the determination The method was simple and quick,it meets the demands for the routine analysis in ferrous factory |
