Bentonite-supported nanoscale zero-valent iron (B-nZVI) was synthesized using liquidphase reduction. The orthogonal method was used to evaluate the factors impacting Cr (VI) removal and this showed that the initial concentration of Cr (VI), pH, temperature, and B-nZVI loading were all importance factors. Characterization with scanning electron microscopy (SEM) validated the hypothesis that the presence of bentonite led to a decrease in aggregation of iron nanoparticles and a corresponding increase in the specific surface area (SSA) of the iron particles. B-nZVI with a 50% bentonite mass fraction had a SSA of 39. 94m2/g, while the SSA of nZVI and bentonite was 54. 04 and 6. 03 m2/g, respectively. X-ray diffraction (XRD) confirmed the existence of Fe0 before the reaction and the presence of Fe (II), Fe (III) and Cr (III) after the reaction. Batch experiments revealed that the removal of Cr (VI) using B-nZVI was consistent with pseudo first-order reaction kinetics. Finally, B-nZVI was used to remediate electroplating wastewater with removal efficiencies for Cr, Pb and Cu>90%. Reuse of B-nZVI after washing with ethylenediaminetetraacetic acid (EDTA) solution was possible but the capacity of B-nZVI for Cr (VI) removal decreased by approximately 70%.
