Hexavalent chromium (Cr(VI)) is a typical heavy metal pollutant, making its removal from wastewater imperative. Although nanosized zero-valent iron (nZVI) and graphene-based materials are excellent remediation materials, they have drawbacks, such as agglomeration being difficult to recycle. A facile synthesis method for decorating reduced graphene oxide (rGO) with ultrathin nZVI (within 10 nm) was explored in this study order develop an effective tool Cr(VI) detoxication. Cu particles were doped these composites electron-transfer enhancement verified improve the rate by 2.4~3.4 times. Batch experiments conducted at different pHs, initial concentrations, ionic strengths, humic acid (HA) concentrations. From observations, it found that condition appearance of rGO enhanced treatment capacity. This procedure fitted pseudo-second-order model, existence NaCl HA impeded some extent. could be detoxified into Cr(III) precipitated on surface. Combining analyses, kinetics study, characterizations before after reaction, mechanism further discussed complex process involving adsorption, reduction, precipitation. The maximum capacity 156.25 mg g−1 occurred condition, providing potential method.
