Electron donor limitations reduce microbial enhanced trichloroethene DNAPL dissolution: a flux-based analysis using diffusion-cells.

abstract：:As an effort to better utilize the microbial fuel cell (MFC) technology, we previously proposed an innovative MFC system named M2FC consisting of ferric-based MFC part and ferrous-based fuel cell (FC) part. In this reactor, ferric ion, the catholyte in the MFC part, was efficiently regenerated by the FC part with the ...
