Electrochemical catalytic system can handle real wastewater

Researchers in the US have designed an approach that can generate ammonia from water contaminated with nitrate. It combines the nitrate reduction reaction with Donnan dialysis to show how a troublesome pollutant can be transformed into a valuable product.
