PDA-FeO decorated carbon felt anode enhancing electrochemical performance of microbial fuel cells: Effect of electrode materials on electroactive biofilm.

Anode modification is an effective strategy for enhancing the electrochemical performance of microbial fuel cell (MFC). However, the impacts of the modified materials on anode biofilm development during MFC operation have been less studied. We prepared a novel PDA-FeO-CF composite anode by coating original carbon felt anode (CF) with polydopamine (PDA) and FeO nanoparticles.

Recovery of ammonia nitrogen from landfill leachate using a biopolar membrane equipped electrodialysis system.

In this paper, a laboratory-scale electrodialysis reactor with five compartment cells separated by a bipolar membrane and ion exchange membrane was assembled to remove ammonia nitrogen from landfill leachate as a pretreatment process. The effects of humic acid, magnesium ions (Mg) and calcium ions (Ca) existing in leachate on the removal efficiency of ammonium (NH ) were investigated by using simulated wastewater. The results indicate that humic acid has little impact on ammonium in the presence of an electric field.
