GB/T 8654.1-2007 Manganese metal,ferromanganese-silicon,ferromanganese and nitrogen-bearing ferromanganese—Determination of iron content—The ortho-phenanthrdine spectrophotometric method and the titanium trichloride-potassium dichromate titrimetric method
Abstract
This part of GB/T 8654 specifies the determination of iron content in metallic manganese, manganese-silicon alloys, manganese-iron alloys, and manganese-iron nitrides using the o-phenanthroline spectrophotometry and the titanium trichloride-potassium dichromate titration method. This part is applicable to the determination of iron content in metallic manganese, manganese-silicon alloys, manganese-iron alloys, and manganese-iron nitrides. Among them, the o-phenanthroline spectrophotometry is suitable for the determination of iron content in metallic manganese, with a determination range (mass fraction) of 0.001% to 1.00%; the titanium trichloride-potassium dichromate titration method is suitable for the determination of iron content in metallic manganese, manganese-silicon alloys, manganese-iron alloys, and manganese-iron nitrides, with a determination range (mass fraction) of 1.00% to 35.00%.
