Anthraquinone compound-containing tourmaline, preparation method and application thereof |
| abstract |
Disclosed is an anthraquinone compound-containing tourmaline, a preparation method and an application thereof. By reacting a chloropropyl silane coupling agent and tourmaline, a chloropropyl-modified tourmaline is obtained, which then undergoes a dehydrochloride reaction with an amino group-containing anthraquinone compound under the action of an acid binding agent to obtain a tourmaline that contains an anthraquinone compound at the surface thereof. The obtained tourmaline can significantly accelerate the biological reduction process of azo dyes and nitrates, can be reused, has a wide range of raw material sources, few reaction steps and low costs, and can be widely used in wastewater treatment. |
