NOVELTY - Novel functionalized magnetic oxide granite composite comprises graphene oxide material is loaded with magnetic nanoparticles and beta -cyclodextrin/polyglutamic acid. USE - Novel functionalized magnetic oxide granite composite used for removing estradiol graphene oxide composite material (claimed). ADVANTAGE - Novel functionalized magnetic oxide granite composite is cots-effective, greatly increases adsorption site of magnetic graphite oxide, easy to separate from solution, high economic efficiency and has good absorption effect of estradiol in waste water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing novel functionalized magnetic oxide granite composite, which involves: (A) weighing 0.2 gram 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide and 0.2 gram N-hydroxysuccinimide; (B) adding to aqueous solution contained 0.4 gram beta -cyclodextrin/polyglutamic acid at room temperature for 2 hours; (C) adding above-mentioned magnetic oxidized graphene dispersion and 20 milliliter diethylenetriamine mixed solution to continuously stirred for 6 h in water bath at 80 degrees C; and (D) rinsing with deionized water to neutrallized to obtained composite.
