摘　　要：通过对石墨相C_3N_4的质子化,研制了一种p-g-C_3N_4/Fe_3O_4顺磁性物质,该物质可有效地处理甲基红废水,并在外加磁场存在下简单回收重复使用,降低了废水处理成本.还通过化学方法,考察了p-g-C_3N_4/Fe_3O_4降解甲基红的机理.A paramagnetic photocatalyst（ g-C3N4/Fe3O4）was developed by protonation of graphitic carbon nitride. The obtained catalyst can be easily recycled with external magnetic field.The result shows that the methyl red wastewater can be effectively degraded.So the cost of wastewater treatment can be reduced by recycling. The mechanism on the degradation of organic pollutants under ultraviolet light was studied by adding trapping agent.
