研究了微碱法(2NaOH:FeSO4=1.15)条件下合成超细α-FeOOH反应过程的动力学。主要考察了Fe(Ⅱ)初始浓度、反应温度(T)、搅拌强度(r)、空气用量(V)、氧气分压以及碱铁比(R)对反应速率的影响。试验得出了在形核阶段对Fe(Ⅱ)为0级反应，对氧分压亦为0级反应，求出了反应的活化能为12．25kJ.mol-1

An ultra-fine α- FeOOH powders was synthesized by the aerial oxidation in the slight alkaline = 1.15) solution. The effect factors on the reaction rate such as the initial concentration , the reaction temperature (T), the agitation rate(r), the air - flow rate(V), the partial pressure of oxygenand the ratio of 2NaOH to (R) were investigated The reaction is a zero order for both Fe(Ⅱ) and oxygen partial pressure during nacleation. The activction energy of reaction is12.25kJ.MOL-1
