Abstract

Effect of different cations to the formation of iron oxyhydroxide was studied using $M\ddot{o}ssbauer$ spectroscopy, X-ray diffraction (XRD) and BET. Redox Potential and pH were measured for the determination of the internal reaction rate, as well. The phases of iron oxyhydroxide could not be the same with each other, due to the presence of different cations in solution. Although the oxyhydroxide compound was composed of the same phases, the fraction of each phase was different from each other. The internal reaction rate was varied by the substitution of cation. It could be a cause of the different phase and particle size of oxyhydroxide compound.
