A loading composite Fe_xCe_(1-x)/γ-Al_2O_3(x = 0,0.5,1) catalyst were synthesized in incipient wetness impregnation method with pseudo-boehmite calcined at 550 ℃ as support and Fe(NO_3)_2 · 9H_2O and Ce(NO_3)_2·6H_2O as precursors.The Fe/γ-Al_2O_3,Ce/γ-Al_2O_3 and Fe_(0.5)Ce_(0.5)/γ-Al_2O_3 catalysts were characterized by SEM,TEM and N_2 adsorption,and the degradation performance of the ceramic printing wastewater was investigated over the composite Fe_(0.5)Ce_(0.5)/γ-Al_2O_3 catalyst at reaction temperature of 160,180,200 and 220 ℃.The results show that Ce-modified Fe_(0.5)Ce_(0.5)/γ-Al_2O_3 catalyst exhibit evenly distributed sizes about 30 nm.The decolorization efficiency of ceramic printing wastewater was as high as 99.1%at 200 ℃ reaction temperature,and the chroma was 70 multiples,which achieve the secondary emission standard under Integrated Wastewater Discharge Standard (GB8978-1996).
