▎ 摘  要

NOVELTY - Removing endocrine disruptors in water by using iron and manganese double-phase-doped graphene comprises (i) mixing the monopersulfate with the water after pretreatment; (ii) regulating a reaction pH value; (iii) preparing iron and manganese double-phase-doped graphene; (iv) adding iron and manganese double-phase-doped graphene; and (v) separating iron and manganese double-phase-doped graphene by adopting an external magnetic field. USE - The method is useful for removing endocrine disruptors in water by using iron and manganese double-phase-doped graphene (claimed). ADVANTAGE - The method aims at solving the problems of low removal efficiency and high cost of the existing method for removing the endocrine disruptors in the water. DETAILED DESCRIPTION - Removing endocrine disruptors in water by using iron and manganese double-phase-doped graphene comprises (i) mixing monopersulfate with pretreated water, stirring at 160-250 revolutions per minute for 20-45 minutes, to obtain monopersulfuric sulfate and water pre-mixed solution, where the monopersulfate is mono ammonium persulfate, mono sodium persulfate and/or calcium monopersulfate; (ii) under stirring speed of 150-200 revolutions per minute, adjusting the pH of monopersulfuric sulfate and water pre-mixed solution using 0.1-100 mol/l perchlorate and 0.1-100 mol/l sodium hydroxide solution to 6.5-7.5; (iii) preparing ferromanganese duplex doped graphene; (iv) adjusting the pH of monopersulfate and pretreatment water mixed solution using ferromanganese biphasic doped graphene, reacting for 15-240 minutes, to obtain ferromanganese containing graphene doped biphasic water; and (v) separating ferromanganese containing graphene doped biphasic water using external magnetic field, recycling iron and manganese-doped graphene duplex, filtering iron and manganese-doped graphene duplex using 0.45 mu m glass fiber membrane pore size, drying the duplex at 50-75 degrees C for 12-48 hours, and using the regenerated ferromanganese duplex doped graphene for removing endocrine disruptors in water.
