Abstract

The invention discloses a method for preparing a cyclodextrin / reduced graphene oxide modified ferroferric oxide compound and application of the compound in water treatment. The method includes following steps: dispersing 20mg of graphene oxide into 20ml of ethylene glycol, using an ultrasonic cell breaker to treat for 30min to form uniform dispersion liquid, adding 0.4g of FeCl3 6H2O, 1.13g of sodium acetate, 0.3g of polyethylene glycol and 20mg of beta-CD into the dispersion liquid, and magnetically stirring for 30min; transferring mixed dispersion liquid into a reaction kettle for reaction at 200 DEG C for 8h; using deionized water and alcohol to repeatedly wash obtained precipitate, and vacuum-drying at 50 DEG C for 12h; grinding a final product for standby use. A catalyst prepared by the method has excellent catalytic performance, can remove pollutants within short time, is suitable for wide pH range and reusable and is expected to be used for degrading difficult-to-remove pollutants.
