GB/T 1508-2002 provides the potassium dichromate Titrimetric method and the o-phenanthroline Spectrophotometric method, spec-trophotometry, for the determination of total iron content in manganese ores. Suitable for all kinds of manganese ore samples. The potassium dichromate Titrimetric method is based on oxidation reduction reaction, and the iron content is determined by titration of ferrous ions with potassium dichromate; the o-phenanthroline spectrophotometry uses the Absorbance of iron and o-phenanthroline complexes to determine. The standard specifies the equipment required for the two methods, such as Burette, spectrophotometer, etc., and specifies the preparation of reagents. Detailed description of Sample Handling steps and standardized operation procedures. According to this standard, the total iron content can be accurately determined, providing key data for the mass evaluation of manganese ores and industrial applications.
