Effect of NaX zeolite-modified graphite felts on hexavalent chromium removal in biocathode microbial fuel cells.
30/05/2019
Abstract
NaX zeolite-modified graphite felts were used as biocathode electrodes in microbial fuel cells (MFCs) for reducing hexavalent chromium (Cr(VI)). The results showed that the NaX zeolite-modified graphite felts are excellent bio-electrode materials for MFCs, and that a large NaX loading mass, leads to a superior performance. The maximum Cr(VI) removal rate was 8.2 times higher than that of the unmodified control. The improvement was ascribed to the strong affinity that NaX zeolite particles have for microorganisms and Cr(VI) ions.
