主　　题：Antipyrine Lanthanum Catalyst Fenton-like process 

摘      要：The aim of this study was to synthesize a novel lanthanum(La)doped catalyst and to investigate antipyrine removal in wastewater using the Fenton-like process with the *** La-doped Co-Cu-Fe catalyst was synthesized using the modified hydrothermal *** showed that the Ladoped catalyst had higher specific surface area and lower particle size than the catalyst without La doping(i.e.,the control)(267 vs.163 m2/g and 14 vs.32 nm,respectively).Under the conditions of catalyst dosage 0.5 g/L,H2O2 concentration 1.70 g/L,and NaHCO3 0.1g/L,the antipyrine removal within 60 min using the Fenton-like process with the La-doped catalyst was much higher than that with the control(95%vs.54%).The hydroxyl radical concentration with the La-doped catalyst within 60 min was two times higher than that with the control(49.2 vs.22.1 gg/L).The high catalytic activity of La-doped catalyst was mainly attributed to its high specific surface area based on the X-ray photoelectron spectroscopy *** La-doped catalyst should have great potential to remove antipyrine in wastewater using the heterogeneous Fenton-like process.
