Microbial electrolytic disinfection process for highly efficient Escherichia coli inactivation

“…Current was recorded by a battery testing system (CT-4008W, Neware Battery Testing System, China). The hydrogen peroxide concentration was measured by UVvis spectrophotometry (Spectronic 20D+, Thermo Scientific) at 400 nm wavelength [20]. The pH was measured by a pH meter (PHM 92 lab pH meter, Radiometer, Denmark).…”

Microbial electrolysis cell as an emerging versatile technology: a review on its potential application, advance and challenge

“…The cathode potential has been identified as a key parameter for H 2 O 2 production in the MEC . Li et al . were the first to develop an innovative method for cost‐effective production of H 2 O 2 by using a microbial reverse‐electrodialysis electrolysis cell.…”

“…(B) Electrical potential generated by the exoelectrogens and the salinity‐gradient between salt water and fresh water were utilized to drive the high‐rate H 2 O 2 production (figure redrawn after Ki et al . and Li et al …”

“…87 The cathode potential has been identified as a key parameter for H 2 O 2 production in the MEC. 88 Li et al 89 were the first to develop an innovative method for cost-effective production of H 2 O 2 by using a microbial reverse-electrodialysis electrolysis cell. In this system, the electrical potential generated by the exoelectrogens and the salinity gradient between salt and fresh water were used to drive a high rate of H 2 O 2 production ( Fig.…”
