Abstract

Poly(m-phenylenediamine) grafted graphene oxide composite (P-GO) was successfully synthesized by diazotization reaction and in-situ oxidative polymerization method.The structure and morphology of P-GO were characterized by scanning electron microscope (SEM),Fourier transform infrared spectra (FT-IR),X-ray photoelectron spectroscopy (XPS) and Thermogravimetric analysis (TG).Then,the effects of pH,contact time and initial Cr(Ⅵ) ion concentration for the adsorption behavior of Cr(Ⅵ) on P-GO were investigated.The results shown that poly(m-phenylenediamine) was successfully grafted onto the surface of graphene oxide.The adsorption kinetics and equilibrium adsorption isotherm of P-GO for Cr(Ⅵ) fitted the pseudo-second-order kinetic model and Langmuir isotherm model well,respectively.And the maximum adsorption capacity reached 118.34mg/g,which was much higher than that of GO.The high adsorption efficiency of P-GO for Cr(Ⅵ) was attributed to the introduction of a large number of nitrogen-containing functional groups on the surface of GO after grafting of poly(m-phenylenediamine).
