Lead(II) Removal at the Bioanode of Microbial Electrolysis Cells

Abstract Advanced treatment, such as tight membrane filtration and ion exchange, can be applied for Pb 2+ removal from wastewater but these methods are expensive with a high demand for electric energy and chemicals. Microbial electrolysis cells (MECs) are an emerging wastewater treatment technology and MECs can remove Pb 2+ by reduction and precipitation at the cathode and biosorption at the anode; however, reduction at the anode has not been …
