p-Phenylenediamine functionalized magnetic graphene oxide nanocomposites (PPD-MGO) were prepared and utilized in the adsorption and removal of bisphenol A in aqueous solution. The novel nanomaterials were characterized by transmission electron microscopy (TEM), Fourier infrared spectrometry (FT-IR) and vibrating sample magnetometer (VSM). The factors affected the adsorption of bisphenol A including adsorption time, temperature and pH of solution, adsorption kinetics and isotherms were all investigated. The results showed that PPD-MGO nanomaterial exhibited good adsorption ability for bisphenol A and good resuability. The maximum adsorption capacity reached 155.0 mg g-1 at 45?C and pH 7. The removal rate was 99.2 % after three times of adsorption with new nanomaterials. After five cycles adsorption, the adsorption capacity of PPD-MGO remained at 94.0 %. The adsorption of bisphenol A was found that fitted pseudo second order kinetics equations and the Freundlich adsorption model. The experimental results showed the PPD-MGO nanomaterial had a good adsorption ability to remove organic compounds in aqueous solution.
