The degradation rate was 81.9% after 3 hours, and the recovery rate of nanoparticles was 88.4%. nanoparticles were utilized on degradating 20 mg/L TNT waste solution under ultraviolet light. The morporous structure was demonstrated by the N2 adsorption-desorption analysis results. The results of XRD, TEM and magnetic characterizations showed that the magnetic cores were magnetite and the functional layer was anatase with the saturation magnetization of the overall nanoparticles was 46.5 emu/g. The nanoparticles were obtained through high temperature carbon reduction method and gel-sol method. Aimed at the complicated composition, high emission and poison of the TNT wastewater,a degradation method based on efficient and recoverable nanoparticles through UV photocatalysis was reported.
