Abstract
The formation of goethite in the basic medium is simulated by stirring, in the presence of air, a mixture of FeSO4.7H2O and NaOH in the 1∶5 ratio at different initial concentration C of ferrous ions. The initial oxidation product is ferrous hydroxide and its further oxidation leads mainly to goethite through active α′-FeOOH. The kinetics of the process is studied from Mössbauer spectra.
