内容記述 | Ferric hydroxide (Fe(OH)_3) gel, prepared from FeCl_3 and NaOH solutions, was aged at 100℃ in the presence and absence of sulfate ions to examine the effect of the sulfate ions on the conversion process of condensed Fe(OH)_3 gel to β-FeOOH and α-Fe_2O_3 particles. Fine particles and supernatant solution were sampled from the aged suspensions containing colloidal particles. Powder X-ray diffraction (XRD) profiles and transmission electron microscopic (TEM) observation showed that β-FeOOH was formed from the gel and subsequently converted into α-Fe_2O_3. The addition of sulfate ions accelerated the β-FeOOH formation from the gel and delayed the conversion from β-FeOOH to α-Fe_2O_3. The concentration changes of sulfate and chloride ions in the supernatant solution phases were in agreement with the conversion from Fe(OH)_3 gel to β-FeOOH and α-Fe_2O_3 particles. | |||||
