Toxicity monitoring signals analysis of selenite using microbial fuel cells.

Microbial fuel cells (MFCs) based biosensors are widely studied to environmental monitoring. The suitable responsive signal is important for microbial electrochemical sensors. However, the responsive signals of toxins have not been investigated in detail.

Architecting an indirect Z-scheme NiCoO@CdS-Ag photocatalytic system with enhanced charge transfer for high-efficiency degradation of emerging pollutants.

Bimetallic oxides with spinel structure show great prospects in the photocatalysis owing to many active sites. Herein, a novel 500NiCoO@CdS-5%Ag composite was fabricated via a feasible strategy. Interestingly, the combination with NiCoO could significantly enhance the absorption ability of CdS for visible light.

Treatment of Oil Wastewater and Electricity Generation by Integrating Constructed Wetland with Microbial Fuel Cell.

Conventional oil sewage treatment methods can achieve satisfactory removal efficiency, but energy consumption problems during the process of oil sewage treatment are worth attention. The integration of a constructed wetland reactor and a microbial fuel cell reactor (CW-MFC) to treat oil-contaminated wastewater, compared with a microbial fuel cell reactor (MFC) alone and a constructed wetland reactor (CW) alone, was explored in this research. Performances of the three reactors including chemical oxygen demand (COD), oil removal, and output voltage generation were continuously monitored.
