Description

The infrared absorption spectra of α-ferric oxyhydroxides with different aging times were studied in detail. As a result, a linear correlation was found between the frequency of variable bands of 610?643 cm-1 and the absorbance of 890cm-1 band of α-ferric oxyhydroxides. The correlation was further applied to the determination of the content of α-ferric oxyhydroxides in rusts and iron ores. The analytical values obtained by the present method were in good agreement with those by the thermogravimetric analysis.
