In this experiment, ZSM‐5 molecular sieves are prepared by hydrothermal synthesis and modified impregnation with Fe, La, Ce loading. X‐ray diffraction, photon‐electron spectroscopy, scanning electron microscopy show that elements successfully loaded onto the surface of material, area Fe‐La‐Ce‐ZSM‐5 is 241.66 m 2 g −1 . A systematic study on adsorption Congo red solution carried out using it found through data process more in line Langmuir proposed second‐order kinetic model, theoretical saturated capacity 2669.19 mg The recycled four times still has than 60 % removal performance for high‐concentration solution. results experiment excellent dye wastewater.
