Abstract：A novel quaternary amine-modified waste newspaper fiber (CWNF) was prepared with epichlorohydrin and trimethylamine and characterized by fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), EDS, thermogravimetric analysis (TGA) and BET surface area analysis. The adsorption property of CWNF for Cr (VI) from aqueous solution was studied. Results showed that the adsorption equilibrium time was about 60min, and the maximum adsorption capacity was 38.66mg/g at pH 1and increased about 59.88% compared to that of waste newspaper fiber (WNF) (24.18mg/g). The adsorption of Cr (VI) on the CWNF was found to follow the pseudo-second-order kinetics equation and agree well with both Langmuir and Freundlich adsorption isotherm model.
