Mechanisms of Heavy Metal Separation in Bioelectrochemical Systems and Relative Significance of Precipitation

Heavy metal pollution is a severe environmental issue. Most heavy metals are toxic and can threaten human health. Conventional methods such as precipitation and adsorption have been used to separate heavy metals from aqueous solution. Due to the high energy and chemical cost of conventional methods, there is a need for new cost-effective and sustainable technologies to separate heavy metals. Bioelectrochemical systems (BES) have been reported …
