Perchlorate Removal in Microbial Electrochemical Systems With Iron/Carbon Electrodes [PDF]

Frontiers in Chemistry, 2019
Perchlorate removal was tested in the cathode chamber of microbial electrochemical systems (MESs). Dual-chambers MESs were constructed and operated in batch mode with four kinds of cathode materials including Fe/C particles (Fe/C), zero valent iron particles (ZVI), blank carbon felt (CF), and active carbon (AC).

The electrochemical perspective of bioelectrocatalytic activities in microbial electrolysis and microbial fuel cells

Energy Reports, 2019
Transforming organic waste directly into electricity or indirectly into sources of hydrogen fuel is credible through exoelectrogen microorganisms grown on the anode or cathode that catalyze electrochemical reactions. In this review, we discuss the origin
