Funded by multiple grants from the U.S. National Science Foundation, researchers created a functional sponge that can soak up certain pollutants from water and then release them on demand, presenting a reusable and low-cost solution for cleaning storm runoff while simultaneously recovering valuable metals like zinc and copper, as well as phosphate.

Using surface iron oxide nanoparticles specialized for capturing specific contaminants, the sponge collects the minerals and then discharges them only when triggered by changes in pH, and it can be used multiple times. The findings were achieved by researchers at Northwestern University and published in the American Chemical Society’s journal Environmental Science and Technology Water.

“The technology can be used as a universal sorbent or ‘catch-all,’ or it can be tailored to certain groups of contaminants like metals, plastics or nutrients,” says Vinayak Dravid, a research author and Northwestern professor of materials science and engineering. In previous iterations, the sponge material has successfully pulled lead, microplastics and oil from water.

Industrial manufacturing and agriculture, in particular, experience mineral and fertilizer loss due to runoff, leaving valuable nonrenewable resources as pollutants in bodies of water. Those resources include heavy metals like zinc and copper and also phosphate.
