摘要：
The main objective of this study was to synthesize a nanocomposite (NC) of Microbial Cellulose/nano-Fe3O4 @Polypyrrole (MC/nano-Fe3O4@PPy) in two steps, including preparation of MC/Fe3O4 and polymerization of magnetic/microbial cellulose with pyrrole and use this adsorbent for the removal of Cr(VI) from an aqueous solution. For this aim, the adsorbent was analyzed through Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), Brunauer-Emmett-Teller (BET), the field emission scanning electron microscopy (FESEM), and thermogravimetric analysis (TGA). The efficiency of chromium (VI) [Cr (VI)] removal was obtained by 99.76% under optimum conditions, including the pH 3, 200 mg/L (VI) concentration, 5.0 g/L MC/nano-Fe3O4@PPy at a temperature of 30 degrees C in 180 min. The isotherm model was fitted with Freundlich and Langmuir adsorption isotherms and kinetic models was fitted with the first-order kinetic. The thermodynamic results suggested the endothermic pattern for Cr (VI) adsorption on MC/nano-Fe3O4@PPy.
