REDOX-BASED ELECTROCHEMICAL ADSORPTION TECHNOLOGIES FOR ENERGY-EFFICIENT WATER PURIFICATION AND WASTEWATER TREATMENT

摘要

Water scarcity, both economic and physical, affects close to a third of the world population. Efficient, affordable and robust purification technologies are needed for a range of separation contexts, from point-of-source treatment or remote in-situ purification devices to large-scale, centralized wastewater treatment facilities. Micropollutants (e.g., organic endocrine disruptors, pesticides, household chemicals, dyes and heavy metal cations) pose a particularly vexing problem in wastewater treatment, since current technologies suffer from high energetic penalties and performance limitations when confronted with pollutants at these very low concentrations (nM to μM), often in the presence of excess competing species.
