Abstract—Degradation of polyacrylamide(PAM) in aqueous on the heterogeneous catalyst instead of Fe ions catalyzed
solution was studied by using Fe2O3/Al2O3 or Fe2O3/carbon as position of hydrogen peroxide, such as Metal Oxide,
heterogeneous catalyst in the presence of H2O2. In order to known as the Fenton-like [8,9] reaction. Compared with
improve the catalytic activity, Effects of catalyst preparation Fenton reaction, The Fenton-like reaction Has obvious
conditions as impregnated materials, acid dipping and adding advantages: catalysts are easy to be recovered and a
trace elements to catalyst activity were studied in the negligible amount of catalysts into the liquid phase. Ting
experiment. It was observed pared with Fe2(SO4)3, Liu et al [1]. prepared heterogeneous Fe(III)-SiO catalysts
Ⅲ 2
the Fe( ) catalyst prepared with Fe(NO3)3 as the impregnated for the photo-Fenton degradation of polyacrylamide in
material showed better catalyst activity. The Fe2O3/Al2O3 and aqueous solution essfully, and about 94% degradation
Fe2O3/carbon catalysts prepared with Acid immersion showed of PAM
