H3PW12O40 supported Fe-bentonite (HPW-Fe-Bent) was prepared by an impregnation method. Catalyst characterization showed H3PW12O40 and iron species were successfully immobilized on HPW-Fe-Bent. Photo-Fenton degradation of methyl orange (MO) by HPW-Fe-Bent as heterogeneous catalyst was studied. The impacts of various operating parameters on degradation ratio were analyzed. The results showed HPW-Fe-Bent used as heterogeneous catalyst in photo-Fenton process had a wide applicable range of pH and temperature. Moreover, HPW-Fe-Bent had a long-term stability for use, and retained almost all of its catalytic stability and activity after five recycling times. The possible mechanisms involving in photo-Fenton process were presented in paper. (C) 2011 Elsevier BM. All rights reserved.
