摘要: 基于膜理论,分析了含有超细Fe(OH)_2颗粒的淤浆中氧气的传递速率。利用数值解与近似解法给出了增强因子与反应-扩散模数间的关系,两者符合很好。实验验证了Fe(OH)_2的氧化速率与其粒径成反比。Abstract: The problem of oxygen mass transfer in ultrafine Fe(OH)_2 slurry was analyzed via film theory. Numerical and approximate solutions were given to set up the relation between enhancement factor and diffussion modul. The result showed that Fe(OH)_2 oxidation rate is reciprocal to its diameter and was verified by experiment.
