| 内容記述 | The oxidation of FeSO4 solution by O2 gas was studied at pH between 6.0 and 7.7. The oxidation was presumed to be composed of the sequential steps of dissolution of O2 gas and reaction between Fe2+ ion and O2, and the rate determining steps were pursued. The rate of oxidation increased with pH. In the region of pH (at 25℃ and Re 4000), the overall rate was controlled by the transferring rate of 02 in the liquid boundary film adjacent to the gas bubbles. The rate of reaction between Fe2+ ion and O2 was revealed to be proportional to the 4/3th power of C(OH-). At the temperature below 15℃, (at pH 6.8 and Re 1000), the overall rate was affected by both rates of mass transfer of O2 and chemical reaction. From the calculated rate constant of the reaction between Fe2+ ion and O2, the activation energy of 21 kcal/mole was obtained. The overall rate of oxidation increased with the flow rate of gas stream (at 25℃ and pH 6.8). At lower Reynolds number, the oxidation was mass transfer control. When Reynolds number was higher, it was of mixed control of mass transfer of O2 and chemical reaction. | |||||
