Tourmaline having a surface-grafted anthraquinone compound, a preparation method and an application. Reacting an epoxy silane coupling agent with tourmaline, obtaining epoxy modified tourmaline, then reacting with an amino-containing anthraquinone compound using high activity between an epoxy group and an amino group, obtaining tourmaline having a surface-grafted anthraquinone compound. Using tourmaline having a surface-grafted anthraquinone compound can significantly accelerate azo dye degradation, and it can be reused; in addition, raw material sources are broad, there are few reaction steps and costs are low, and the invention may be broadly used in treatment of wastewater containing azo dyes, nitrates, etc. |
