Influence of sodium polyanethol sulphonate on the morphology of β-FeOOH particles obtained from the hydrolysis of a FeCl3 solution
Influence of sodium polyanethol sulphonate on the hydrolysis of 0.1 M FeCl3 solution at 90 °C has been investigated. In the absence of this polymer different shapes of submicron particles such as needles, X- and Y-shaped particles were obtained. The experimental conditions for the formation of spherical particles of micron dimensions, in the presence of sodium polyanethol sulphonate, were determined. At relatively high concentration of the polymer, large particles of irregular shape were dominant. FT-IR spectra (mid + far) of these particles showed the characteristic β-FeOOH phase and also indicated the incorporation of polyanethol sulphonate chains into the microstructure of the particles. The phenomenology of this process was discussed
