We present an efficient Cu2+ electrosorption based on poly(m-phenylenediamine)/reduced graphene oxide (PmPD/RGO), which is formed via simultaneous reduction of graphene oxide (GO) to RGO and polymerization of m-phenylenediamine (mPD) to PmPD. The as-prepared PmPD/RGO composites were characterized by transmission electron microscopy (TEM), Fourier transform infrared (FT-IR) spectroscopy, thermo gravimetric analysis (TGA), and X-ray photoelectron spectroscopy (XPS). The electrosorption behaviors of Cu2+ on the PmPD/RGO electrode were investigated in detail, and the results demonstrated that the PmPD/RGO electrode exhibited a favorable performance for the removal of Cu2+. Due to the excellent electrical conductivity and mechanical properties of RGO, the electrosorption of Cu2+ based on the PmPD/RGO is superior to that on the PmPD. (C) 2015 Elsevier Ltd.
