Abstract

Using carbon fiber (CF) as carriers and sodium carboxymethyl cellulose (CMC) as modifiers, nano zero valent iron (nZVI) was prepared and characterized by Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD). The effects of the different materials, the initial solution pH, and so on, were investigated. The results show that the modified nZVI has better dispersion and stronger antioxidant activity. CF-CMC-nZVI was proved the best to remove Cr (VI). The process of removal Cr (VI) by CF-CMC-nZVI was line with the Langmuir adsorption isotherm and maximum adsorption was 217.04 mg/g.
