Electrosorptive disinfection of Escherichia coli (E. coli) aqueous solutions by activated carbon monolith electrodes

Electrosorption, which can be defined as adsorption onto the surfaces of charged electrodes, has been developing as an efficient and environmentally friendly technology for removing toxic pollutants from aqueous solutions. In this study, an industrial process was used for the fabrication of activate...
