Sažetak
The effect of AOT (sodium di-2-ethylhexyl sulfosuccinate) on the formation and microstructure of α-Fe2O3 by the forced hydrolysis of FeCl3 solutions was investigated. The precipitates formed were characterized by XRD, 57Fe Mössbauer, FT-IR and optical spectroscopies, and also with FE-SEM. The presence of AOT influenced the shape of β-FeOOH particles and led to the formation of microporous α-Fe2O3. The preferential adsorption of sulfonate/sulfate groups played an important role in these effects. Generally, the 57Fe Mössbauer and optical spectra were sensitive to low crystallinity, as well as to the particle size and shape.
