Sažetak
Iron oxides (group name) were precipitated by the hydrolysis of Fe(NO3)3 solutions in the presence of urotropin (hexamethylenetetramine). In an acidic medium at elevated temperature, urotropin undergoes hydrolysis with a gradual release of OH ions. The precipitation time varied between 5 hours and 21 days. The typical IR bands of the iron oxide phases were identified and used, together with XRD, to monitor phase changes in the precipitates. At the beginning of the precipitation process an amorphous phase was dominant and with prolonged time of Fe hydrolysis a-FeOOH was formed. a-FeOOH transformed to a-Fe2O3 by the dissolution/reprecipitation mechanism. The concentration effect of urotropin on the phase composition of the precipitates after 7 days of aging was observed with XRD, FT-IR and 57Fe Mössbauer spectroscopies.
