Currently, electrochemical methods used to remove heavy metal ions from industrial wastewater is both energy-consuming and expensive. Thus, a novel, self-powered recovery system of heavy metal ions was designed and constructed. Electrons produced during the anodic oxidation of organic matter were harnessed to power the cathodic reduction reaction of copper ions. An exopolymeric methyl cellulose coating was used to enhance biofilm formation, while a non-toxic and biodegradable cathodic electrolyte was created to further optimize system performances. This system requires no external energy input to power the recovery of Cu2+, prevent environmental heavy metal contamination, and generate an excess of electricity.
