Example Embodiment
[0018] A method for producing graphene organically modified bentonite particles for humic acid treatment in water, including specific steps:
[0019] (1) Mix an appropriate amount of sodium bentonite and cetyltrimethylammonium bromide according to the ratio of 100g sodium bentonite to 22g cetyltrimethylammonium bromide, and add 8 times the total amount Deionized water, heated in a water bath at 70°C, stirred at 250 rpm for 3 hours, after the reaction is completed, the product is filtered, washed with deionized water twice, dried in an oven at 105°C, and ground Powdered for use;
[0020] (2) Add graphene to deionized water according to the material-to-liquid ratio of 1:1000, and ultrasonically disperse for 3 hours to uniformly disperse graphene in deionized water to obtain a graphene dispersion; the organic modification prepared in step (1) Bentonite was added to the graphene dispersion, placed in a microwave reactor, and oscillated at 600W microwave power for 50 minutes. After the...
