METHOD FOR PREPARING TOURMALINE CONTAINING ANTHRAQUINONE COMPOUND BY MEANS OF THIOL-ENE CLICK CHEMISTRY AND APPLICATION THEREOF

摘要

The present invention relates to the field of water treatment for wastewater containing pollutants, and specifically relate to a method for preparing tourmaline containing an anthraquinone compound by means of thiol-ene click chemistry and an application thereof. A mercaptopropyl silane coupling agent reacts with tourmaline to obtain mercaptopropyl-modified tourmaline, and the mercaptopropyl-modified tourmaline then undergoes a thiol-ene click chemistry reaction with an allyloxy-containing anthraquinone compound to obtain tourmaline the surface of which contains the anthraquinone compound. The tourmaline the surface of which contains the anthraquinone compound may significantly accelerate the degradation of azo dyes and may be used repeatedly. Furthermore, the sources of the raw materials are broad, there are few reaction steps and costs are low, and said tourmaline may be widely used in the treatment of wastewater containing azo dyes and nitrates.
