Zero liquid discharge and salt recovery from heavy metal wastewater via hollow-umbrella hydrogel solar evaporation.
The sustainable treatment of heavy metal-laden industrial wastewater toward zero liquid discharge (ZLD) requires simultaneous water purification, heavy metal immobilization, and salt recovery. Here, we demonstrate a hollow-umbrella hydrogel evaporator addressing all these needs within a single platform. Fabricated from...
