Abstract The iron oxide/bentonite was prepared through a reaction of a solution of OH-Fe salt with bentonite clay dispersion. BET, XRD and HRTEM were used to study its surface area, microstructure, and average particle size. The iron oxide/bentonite nano composite was developed as the heterogeneous catalyst for successful discoloration and mineralization of dye rhodamine B. And the effects of solution pH, H2O2 molar concentration, catalyst loading and initial rhodamine B concentration were studied in detail by photometric method. The process of degradation was traced by UV-Visible spectrum. Besides, the comparison between the heterogeneous photo-Fenton process and homogeneous photo-Fenton process was performed. The result shows that, it has large surface area and mainly consists of high catalytic activity α-Fe2O3. The discoloration ratio is up to 97% and the CODCr removal ratio is 71% after 4 h in the presence of pH 3.0，2.5×10-5 mol·L-1 rhodamine B 100 mL，0.3 g·L-1 catalyst，10 mmol·L-1 H2O2 and UV. The rhodamine B degradating speed of heterogeneous photo-Fenton process is much faster than that of homogeneous photo-Fenton process. The catalyst can be reused after being treated.
