Abstract

A composite of nano-zero valent iron (nZVI) supported on granular activated carbon (GAC) was synthesized through adsorption-reduction method, and its performances used as catalyst of Fenton-like were investigated to degrade methylene blue (MB) in model wastewater. The results show that homogeneous dispersion of nZVI was greatly improved after supported on GAC. In comparison, the composite (nZVI/GAC) has higher removal efficiency of MB than the same amount of nZVI or GAC. Moreover, the pH values increased and leaching iron was reduced after reaction which were help to further processing with low cost. The use of nZVI/GAC composite provided a selective and viable solution for removing MB from water by Fenton-like reaction.
