Description
Rui Wei and co-authors build a smart system that pulls ammonium from wastewater and turns it into fertilizer, while watching its own state by colour. Ammonium waste is both a pollutant and a lost nitrogen resource. Their electrode, made of copper hexacyanoferrate, takes up ammonium with strong selectivity over other ions and high capacity.
The electrode changes colour as it loads and unloads, so camera images plus machine learning give a live read of its state. That read drives flow choices in real time. On real swine wastewater, the system recovered 90.2 percent of ammonium over ten cycles at modest energy cost. The liquid ammonium sulfate made worked in fields about as well as shop products.
