The Preparation,Characterization And Heterogeneous Fenton-Like Catalytic Properties Of The Iron Silicate

The heterogeneous Fenton-like process has a significant advantage in the field of wastewater treatment for its efficient oxidizability to degrade the high concentration and non-biodegradable dye wastewater.It can predict that the development of Fenton-like catalyst with environmental friendly,high efficiency,low energy consumption,and study the dynamics of the treatment of organic wastewater,understand the reaction mechanism and other scientific problems of this system is key to research of that field,and the main direction of future environmental organic pollution control technology.In this work,we synthesized Fe₂?SiO₃?₃,Fe_1.8Cr_0.2?SiO₃?₃ and Fe_1.89Cu_0.21?SiO₃?₃ by low temperature solid state method,and the poly-silicic-ferric was prepared using Na₂SiO₃·9H₂O,FeCl₃·6H₂O by co-polymerization.The physical and chemical properties of catalyst characterized by XRF,XRD,FT-IR,XPS and FESEM.The methylene blue was used as the probe molecule,and the catalytic activity for catalyze H₂O₂ oxidation of MB was evaluated.The effect of pH,H₂O₂ concentration,reaction temperature,catalyst dosage on the catalytic performance of catalyst were investigated.The results shows that all of them are efficient Fenton-like catalyst and can be separated easily.
