Enhanced detection of toxicity in wastewater using a 2D smooth anode based microbial fuel cell toxicity sensor.

ABSTRACT: As the biological recognition element of microbial fuel cell (MFC) toxicity "shock" sensors, the electrode biofilm is perceived to be the crucial issue that determines the sensing performance. A carbon felt and indium tin oxide (ITO) film anode were utilized to examine the effects of anodic biofilm microstructure on MFC toxicity sensor performance, with Pb²⁺ as the target toxicant. The carbon felt anode based MFC (CF-MFC) established a linear relationship of Pb²⁺ concentration (C _Pb²⁺ ) vs. voltage inhibition ratio (IR_2h) at a C _Pb²⁺ range of 0.1 mg L^-1 to 1.2 mg L^-1. The highest IR_2h was only 38% for CF-MFC. An ITO anode based MFC (ITO-MFC) also revealed a lin
