This investigation was carried out on the study of Ferrite formation by aerial oxidation of Fe (OH)₂ suspension of aqueous solution containing heavy metal ions. In this study the optimum reactionary condition of the Ferrite formation in Batch reactor wa studied by aerial oxidation which are subjected to various reaction time and temperature, under the different kinds of R(2NaOH/FeSO₄) Values, pH, Air flow rate, and Fe2⁺/M2⁺ mole ratio. The optimum condition for the Ferrite formation in Batch reactor was such that residence Time was 90 min., Temperature 65°C, pH 11.0, Air flow rate 2.0l/min and Fe2⁺/M2⁺ mole ratio 4.0, which was observed by X-Ray diffraction analysis. The relation R-value, pH and ORP affecting the formation of Ferrite is that the jump step in pH 11.0, when a amount of NaOH is added, is steady state to the formation of Ferrite. Effect of R-value of FeSO₄ and FeCl₂ on the formation of Ferrite in different from each other the optimum condition of the in different from each other the optimum condition of the FeCl₂ is R-value 0.7, pH 11.0 and the FeSO₄ R-value 1.2, pH 11.0.
