采用等体积浸渍法制备非均相 Fenton 反应催化剂 Fe2O3/γ-Al2O3，以对羟基苯丙酸为降解目标物，考察了γ-Al2O3粒径的大小、浸渍时间、焙烧温度、焙烧时间、负载量等因素对催化剂催化活性的影响．通过热重、XRD、电镜扫描对催化剂形貌和特征的分析以及催化反应的结果分析可知，在γ-Al2O3上负载了催化剂 Fe2O3，但 Fe2O3并不均匀，在γ-Al2O3为100～120目，负载量为11.7%，浸渍10,h，焙烧温度为550,℃，焙烧4,h，与60,mg/L的对羟基苯丙酸反应60,min的条件下，催化剂的活性最好，对羟基苯丙酸的去除率可达到70.26%．重复实验说明催化剂的稳定性较好．

Catalyst Fe2O3/γ-Al2O3, in hetergeneous Fenton system was prepared using isometric impregnation. This research took p-hydroxyphenyl propionic acid as degradation target and the effect ofγ-Al2O3,size,dipping time,calcinations tempera-ture,roasting time and load,etc. on the activity of the catalyst was studied. TGA,XRD,and SEM analyses of the catalytic reaction and the results showed that catalyst Fe2O3,was loaded onγ-Al2O3,though not very well distributed. The removal of p-hydroxyphenyl propionic acid of 60,mg/L after 60,minutes reached 70.26% when γ-Al2O3 was 100~120,mesh,loading capacity 11.7%,dipping for 10,h,and the calcination temperature was 550,℃ for 4,h.The activity of the catalyst was best under those conditions. Repeated experiments proved the stability of the catalyst.
