Part 4 of this standard specifies methods for the determination of ferric oxide in limestone, dolomite and metallurgical lime by o-diazephedrine Spectrophotometric method, spec-trophotometry and flame atomic absorption spectroscopy (AAS). The o-diazephedrine Spectrophotometric method, spec-trophotometry is suitable for the determination of ferric oxide content in the range of 0.02% to 4.0%, and the flame atomic absorption spectroscopy (AAS) method is also applicable to this range. These methods provide standardized operating procedures and technical requirements for accurate measurement of ferric oxide content, ensuring the reliability and conformity of the measurement results.
