| Abstract: | Nanoscale zero-valent iron (nZVI)-multiwalled carbon nanotube (MWCNT) was first applied to remove polychlorinated biphenyls (PCBs) from water. The characterization result from scanning electron microscopy, transmission electron microscopy, and X-ray powder diffraction showed that the nZVI was immobilized successfully on the surface or into the network of MWCNTs. The effects of different reaction conditions like temperature, initial pH values, MWCNT-nZVI dosage, and initial PCBs concentrations for the removal of PCBs were evaluated. Comparing to pure nZVI or MWCNT, the MWCNT-nZVI nanocomposites exhibited around 30% higher efficiency on PCBs removal. The removal process obeyed the pseudo-secondary-order kinetics model. By calculating the material balance of Cl- during the degradation of PCBs by MWCNT-nZVI, it demonstrated that MWCNT-nZVI has not only a reducing effect but also an adsorption effect on PCBs. During the reaction, reduction plays a dominant role. The reductive activity of nZVI was efficiently supported by MWCNT, which can accelerate electrons transfer in the composite and greatly enhance the reduction activity of nZVI. At the same time, the reusability and stability of MWCNT-nZVI were considered. Overall, MWCNT-nZVI nanocomposites offer a promising alternative material for the removal of PCBs from water.
