When removing very dilute concentrations of pollutants from water, existing separation methods tend to be energy- and chemical-intensive. A new method was developed that could provide a selective alternative for removing even extremely low levels of unwanted compounds. The method relies on an electrochemical process to selectively remove organic contaminants such as pesticides, chemical waste products, and pharmaceuticals, even when these are present in small, yet dangerous concentrations. The approach also addresses key limitations of conventional electrochemical separation methods such as acidity fluctuations and losses in performance that can happen as a result of competing surface reactions.
