- Abstract:
- The microbial fuel cell (MFC) is a device that converts chemical energy in organic matters into electrical energy directly through the metabolic process of microorganisms, which has a good application and development prospect in the field of toxicity sensors. The theoretical basis, configuration selection, influencing factors for toxicity evaluation, research status and existing problems of MFC as a toxicity sensor were summarized to better guide the development of MFC as a toxicity sensor. The results showed that the types of anode microorganisms, shear rate (volume flow), external resistance, dissolved oxygen and electrical conductivity would directly affect MFC’s effect in evaluating the toxicity of wastewater. It has been applied to assess the toxicity of a specific toxic substance or actual water toxicity. However, scientific problems such as long start-up time to limit research development, not yet achieved qualitative evaluation, poor stability， etc., still need to be solved.
