摘要

The abuse of antibiotics greatly aggravates water pollution. Tetracycline hydrochloride (TC), has been widely used all over the world as a typical antibiotic. In order to dispose of TC, a series of Fe3O4/FeP composite materials were synthesized with the combination of hydrothermal synthesis and partial phosphating annealing method. Meanwhile, the morphology and structural characteristics were investigated using characterization such as diffraction of X-rays (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), electro-chemical impedance spectroscopy (EIS) etc. The dark adsorption and photocatalytic activity of Fe3O4/FeP were investigated comprehensively to remove the target molecule tetracycline. Results indicated that Fe3O4/FeP catalysts have a superior performance on dark adsorption, and good effect of TC degradation. Among synthesized photocatalysts, Fe3O4/FeP-6 (molar ratios of Fe:P at 1:6) possessed the optimized performance in adsorption capacity and photodegradation efficiency (88%) comparing to the other ratios. Furthermore, the stability and reusability of Fe3O4/FeP-6 ensured the cyclic photocatalysis experiment. This synthesized catalyst has proved its potential application in wastewater treatment.
