| Abstract: | A dual-wavelength spectrohotometer method for the simultaneous determination of manganese and chromium in the steel has been described. The conditions of the determination of Mn and Cr,such as the acidity,the amounts of ammonium persulfate amd silver nitrate etc, were investigated in detail. Optimum conditions for the simultaneous determination of Mn and Cr were defined. The present method has been used for determining Mn and Cr in the steel, especially in the ferrochrome with satisfactory results. |
