含磷酸盐Fe(Ⅲ)水溶液的水解动力学研究

STUDY ON HYDROLYTIC KINETICS OF AQUEAUS SOLUTION CONTAINING PHOSPHATE ANIONSFe(Ⅲ)

本文研究了Ｆｅ（ＮＯ３）３－ＮａＨ２ＰＯ４体系水解合成纺锤形α－Ｆｅ２Ｏ３微晶的动力学过程。通过使用似稳定浓度法，根据动力学曲线确定了成核阶段的速率方程，计算了成核过程的活化能，从动力学角度解释了α－Ｆｅ２Ｏ３微晶的形成机理。

おhe kinetic process of synthesis spindle αFe_2O_3 by hydrolysis of Fe(NO_3)_3NaH_2PO_4 system was conducted.The rate equation of nucleation was given by quasistable concentration on the basis of kinetic curves.Activation energy of nucleation was calculated.The formation mechanism of αFe2O3 fine crystal was explained from kinetic point of view.
