“…Metals are difficult to degrade into harmless materials under natural conditions, which can cause serious environmental and human health problems. Most common methods for metal recovery from wastewater include ion exchange, reduction, oxidation, solvent extraction, precipitation, electro‐driven separations and adsorption . However, those methods have major shortcomings such as high cost, unsafety and low efficiency.…”

“…The reduction of these metal ions in the MEC requires energy input at the cathode, but the overall voltage needed is still lower than the conventional electrolysis, since there is a part of the voltage that is supplemented by the anode . MEC configurations and anode/cathode materials and important operational parameters such as metal ion concentration and conductivity should be further investigated to enhance metal recovery efficiency …”

Microbial electrolysis cells (MECs) have been studied in a wide range of potential applications such as recalcitrant pollutants removal, chemicals synthesis, resources recovery and biosensors. However, MEC technology is still in its infancy and poses serious challenges for practical large‐scale applications. To understand the diversified applications of MEC, this review aims to explore MEC applications in the following contexts: an overview of MEC for energy generation and recycling such as hydrogen, methane, formic acid and hydrogen peroxide; contaminant removal, specifically complex organic pollutants and inorganic pollutants; as a sensor; as well as resource recovery. New concepts of MEC technology; configuration optimization; electron transfer pathways in biocathodes, and coupling with other technologies for value‐added applications such as MEC‐anaerobic digestion, MEC‐MFC, MEC‐MDC and bio‐E‐Fenton system are discussed. Finally, challenges and outlooks are suggested. The review aims to assist researchers and engineers to understand the latest trends in MEC technologies and applications. © 2018 Society of Chemical Industry

“…A troca iônica na remoção de metais é datada desde 1940 [71]. Pode ocorrer por meio da utilização de resinas [47,72], e assim corre a transição de íons (positivos ou negativos), presentes entre o efluente e os de carga oposta da resina [73].…”

“…O carvão granular pode ser esquematizado conforme Figura 5 (Adaptado de EPA, 2012 [82]). Carvões ativados podem apresentar diferentes adsorções, uma vez que existem vários métodos de produção desse adsorvente [71]. No estudo de ASUQUO et al, 2017 [80], foi realizada a análise de espectroscopia de raios X por dispersão em energia no carvão ativado comercial, que apresentou 89% de carbono e 10 % de oxigênio [80].…”
