纳米α-Fe_2O_3光催化降解干扰物双酚A的研究

Study on photocatalytic degradation of bisphenol A using α-Fe_2O_3

以纳米α-Fe2O3为催化剂,对光催化降解环境内分泌干扰物双酚A进行了研究,阐述了纳米α-Fe2O3的制备过程及优点,研究了溶液的初始浓度、催化剂投加量、pH值对降解效率的影响,并对降解过程的反应动力学进行了探讨,结果表明BPA的光降解反应符合一级反应动力学规律。

The photocatalytic degradation of bisphenol A, one of the Endocrine Disrupting Chemicals（EI）C） was studied. The photocatalyst was α-Fe2O3. The influences of initial pH value, initial concentrations of BPA and α-Fe2O3 on photodegradation efficiency of BPA were investigated and the photocatalytic reaction kinetic was discussed. The results indicated that the photodegradation of BPA was a first order reaction.
