More Information
Summary:The invention discloses a preparation method of an industrial water treatment material, which is characterized by comprising the steps of grinding and crushing tourmaline ore to obtain tourmaline powder of 2000-25000 meshes, sequentially adding hydrochloric acid and sodium hydroxide to remove impurities, washing with deionized water for 2-3 times, and drying in a vacuum drying oven to obtain tourmaline powder; dissolving alpha-cyclodextrin in dimethylformamide, uniformly stirring to obtain an alpha-cyclodextrin solution, then dispersing the obtained tourmaline powder in the obtained alpha-cyclodextrin solution, carrying out ultrasonic treatment at the temperature of 35-50 DEG C for 30-60 minutes, then filtering, and washing and drying the precipitate to obtain modified tourmaline powder; and putting the obtained modified tourmaline powder into a vinyl acetate-ethylene copolymer emulsion, uniformly stirring, adding potassium permanganate powder, continuously uniformly stirring, putting the mixture into a calci
