A novel microbial - Bioelectrochemical sensor for the detection of n-cyclohexyl-2-pyrrolidone in wastewater

A Sustainable Approach for the Production of Green Energy With the Holistic Treatment of Wastewater Through Microbial Electrochemical Technologies: A Review

“…Moreover, this MFC sensor demonstrated a proficiency to sense acid toxicity (pH ranging from 4 to 6) and heavy metal (Cu 2+ ) toxicity (ranging from 2 to 8 mg L −1 ) (Jiang et al, 2017). Also, other emergent contaminants like 4-nitrophenol, phenol, and n-butanol, n-cyclohexyl-2-pyrrolidone and, different volatile organic matters and pathogens were successfully detected through MFC-based biosensor (Kannan et al, 2019;Godain et al, 2020;Olias et al, 2020). Therefore, removal of organic, inorganic and emerging pollutants from wastewater with recovery of different economically viable resources through METs can abet this technology toward its commercialization (Khoo et al, 2020;Ahmed et al, 2021).…”

Microbial fuel cells for in-field water quality monitoring

“…42 In a similar approach, CuSO 4 and 1cyclohexyl-2-pyrrolidone were independently detected in a mixture of volatile organic compounds by considering the inhibition point of the toxicant in the electron transport chain. 20 Photosynthetic and autotrophic bioreceptors, an interesting option for a sensor that only relies on CO 2 and light to function, are particularly suited to detect photosynthesis inhibitors, such as herbicides. 43 Actually, depending on the mode of action, herbicides can either cause a drop or an increase in the output voltage of the MFC sensor.…”

“…The potential use of MFC technology as a sensor was demonstrated for the first time in 2003 by Kim et al 18 The authors showed that the organic content in the anolyte correlates with the output voltage generated by the MFC, with an outstanding stability in field for up to 5 years. 18 Subsequently, the use of MFC technology has been demonstrated for the monitoring of pH, 19 volatile fatty acids (VFAs), 20 pathogens, 21 copper, 22 chromium, iron and nitrate, 23 cadmium, 24 zinc 25 and pesticides. 26 …”

Microbial Fuel Cells, Concept, and Applications

“…A miniaturised electrochemical toxicity biosensor based on graphene oxide quantum dots/carboxylated carbon nanotubes was also used as a "shock sensor" for evaluating the toxicity of Cd, Hg, Pb, 2,4-dinitrophenol, 2,4,6-trichlorophenol, and pentachlorophenol (Zhu et al 2017). Biosensors using electroactive biofilm were also used for assessing the toxicity of different volatile organic compounds (VOCs) (Santoro et al 2016c;Kannan et al 2019).…”
