IR spectral characteristics of goethite and ferric oxide synthesized with boric acid coprecipitation method showed that compared to goethite, Boron-containing ferric oxide displayed a peak at 1343 cm-1 in IR spectrum, suggesting that Fe-O-B bond existed in the material. Specific surface area of the material was 4 times more than that of goethite, implying that B hinders polymerization of ferric oxide.
