Method for preparing inorganic filler with anthraquinone compound fixed on surface thereof and use thereof |
| abstract |
Disclosed are a method for preparing an inorganic filler with an anthraquinone compound fixed on the surface thereof and the use thereof. A chloropropyl silane coupling agent is reacted with an inorganic filler to obtain a chloropropyl group surface-modified inorganic filler, and same is then subjected to a dehydrochlorination reaction with an amino-containing anthraquinone compound under the action of an acid binding agent, so as to obtain an inorganic filler with an anthraquinone compound fixed on the surface thereof. The inorganic filler with an anthraquinone compound fixed on the surface thereof that is obtained using the preparation method can accelerate the degradation of contaminants such as dyes and nitrates, and can be reused; in addition, same has a wide source of raw materials, few reaction steps, and a low cost, and can be widely used in the treatment of wastewater containing azo dyes, nitrates, etc. |
