Function of Anion in the Synthetic Process of Spindle-shaped α-FeOOH
Source abstract
Abstract
Spindle-shaped α-FeOOH was prepared from FeSO4 and different alkalis or mired alhalisrespectively. The morphology of a-FeOOH was observed with TEM. The result shows that its axisratio related to [OH-], the higher concentration of [OH-], the longer axis ratio; α-FeOOH waslike the ellipsoid with caxbonic concentration increasing, because the short tals became Ionger andxis ratio smaller. The essential cause of formating spindle-shaped α-FeOOH particles was thecoagulation of CO ion bond.
