Effect of initial Cr(VI) concentration on a remanent concentration (insert picture: the changing of removal percentage); b removal capacity of Cr(VI) (T = 303 K, pH = 5.0). c The removal percentage; d the FT-IR spectrum of different composites (T = 303 K, C0 = 10 mg L−1, pH = 5.0) (Curve 1: original PANI/m-FB composites; Curve 2: PANI/m-FB composites after treating Cr(VI); Curve 3: PANI/m-FB composites regenerated with acid); e pseudo-first-order; f pseudo-second-order kinetic model of composites on Cr(VI) removal
